My supervisor said it is impossible to figure an average 4 week r/f if the flight is shorter than four weeks, but i remember doing it on another account. Can you please confirm who is correct, and how to figure it out if I am? Thanks.
- The Media Guru Answers(Wednesday, March 10, 1999 ):
You're correct. There are a few workable approaches to this.
- One says that whatever GRPs run within four weeks are the GRPs that count in figuring an average 4-week R&F, whether these GRPs are spread over one, two or three weeks. So, if you have two weeks at 100 GRP/week you have the same average four week R&F as you would for 200 GRP across four weeks; it could just as well have been 50 GRP/week for 4 weeks or 67 GRP/week for 3 weeks.
The Guru supports the above theory.
A small exception might be made for one week schedules, where actual data shows that, for radio in particular, a given number of GRP run in one week delivers slightly higher reach than the same GRP spread over four weeks, due to listening patterns.
- Another approach uses "when-in" data. Here, if you run 100 GRP/week during your flights and your flights are two weeks in and two weeks out, then you do your R&F as if you had 100 GRP/week for four weeks. Using this theory, you get the same result for 100 GRP/week two in, two out, as you do for two in, four out, which, to the Guru, is clearly quite a different communication level.

I am a student working on a media plan for a new
product in the fast food industry. The restaurant is
well established and my target is 18-34 males. I am in
the Lexington, KY market and wondering what would be a
good reach estimate.
- The Media Guru Answers(Thursday, February 25, 1999 ):
This question lacks most of the necessary information. First, the Guru must assume that you want to know what would be a suitable reach Goal.
Establishing communication goals in a scenario like the one you describe will depend mostly on the competitive climate: what levels are being acheived by the other advertisers seeking the same target for similar products?
At times the standard can be based upon levels that the same advertiser has found to be successful in prior launches, but that too should depend on judging whether the competitive climate this launch faces is comparable to what was faced by the prior successful launch.

As a buyer I have always been given the necessary
information needed to put together a buy. I am
currently in a new position, and I am being asked to
provide information that I've never concerned myself
with before, or gotten involved with the how's or
why's of the decision. I'm in dire need of help.
I have been asked to determine the number of GRP's that
should be used in a proposal for a new client. I have
not received any budget information. The schedule will
run 6-8 months, my demo is A 25-35 and the GRP's
should be spiked during the 1st & final week of each
month. Also, I am to include TV, Cable, and Radio.
My question is:
Do I simply request avails from the various TV & radio
and cable stations within the market, put together a
proposed schedule based on the avail information I
receive, and add up the number of GRP's accordingly?
- The Media Guru Answers(Thursday, February 18, 1999 ):
Congratulations, today you are a media planner. But apparently you are working with people lacking professional advertising experience or perhaps a retail client.
You either need some marketing goals input or you need to suggest some goals and get agreement before proceeding. You have been presented with a question equivalent to "how many pounds of nails are needed to build a building?"
You need to know how big a building, what materials it will be made of, how many nails in a pound, to what use will it be put and how big must it be?
To recommend schedule weights you need either a budget or a communications goal to deliver. In media / marketing terms you need to establish -- whether you are given direction or someone accepts your suggestions:
- What has priority: reach or frequency?
- is there a minimum reach or effective reach to attain; per week, in four weeks, or in total?
- To help answer those questions, if no simple answer is available, you might ask is it a new or established product or service?
- What levels are used by the competition, if any?
- Are there any specific product awareness, ad awareness or sales volume goals?
- (In planning advertising, assume everything is a result of advertising: there is no awareness among people not reached; there are no sales to people who are not aware of the product.)
Knowing all this, you could examine reach frequency and continuity impact of various levels and combinations of your media choices. In other words, you somehow need to establish what must be accomplished by the GRPs, before you can decide how many to use.
It is puzzling, in this great information vacuum, that someone has decided to "spike" certain weeks. Apparently there is some information around which you haven't yet been given.

This is a bit of a theoritical problem.I am currently
working on a shaving cream brand which has been on
decline for a few years now. Currently it has a market
share of 3.9% and is ranked 7th.The markets where it is
doing relatively better are actually the smallest markets,
but here too, it is not better than 5th on market shares.
It has a media budget which is about 1/5th of the biggest
spender, which incidentally is not the market leader.
My dilemma is - in the given scenario, for a relaunch,
where should media focus be - on the overall smaller
markets but where the brand is but marginally stronger
or on the bigger markets for the category, where a greater
potential lies ? The distribution strength is the same in
all markets and no directions have been provided by
the marketing team on priority markets.
Thank you Guru. My name is Abu Huzaifa and i am media planner
in Bombay, India.
- The Media Guru Answers(Friday, January 22, 1999 ):
Firstly, these are really marketing issues, not media issues, but to try to look at it from a purely media perspective, consider:
Think beyond the "bigger opportunity of the larger markets," because the impact you can deliver in a market is important. In other words, do you get more consumer response to 100 GRPs against 2 million people or 200 GRPs against 1 million people?
1. Assume that every impression delivered, no matter the market size, has the same potential to generate sales and / or share growth - where will your budget buy the greatest number of impressions?
2. Assume that the ability of the impressions to generate sales growth is influenced by current share of market. Estimate the value of this effect, plus or minus. Apply this weighting to the impressions you can buy and recalculate sales potential, according to paragraph 1.
3. Or assume that every exposure after the third one (or a level of your choosing) is some degree more effective. How many "effective impressions" can you deliver to each market set?

For a national product launch, what are "typical"
TRP weight levels for network tv, say for a launch
that is scheduled for 8 weeks?
- The Media Guru Answers(Wednesday, January 20, 1999 ):
No such thing. It's a classic case of "it depends".
- What is the category?
- Who is the target?
- Is it a unique product or in a competitive field?
- Will there be any other media / PR / other marketing communications?
- What is consumer awareness of the category?
- Is it a high-involvement or low-interest category?
- Is it from a well regarded parent company or an unknown?
With a new product, you want to drive reach as high as possible with adequate supporting frequency. As a rule of thumb, few would start lower than 100 TRP / week.

Are there any references or research done which support
a recommendation for 2+ reach when tv advertising
strategy is focused on frequency? (I happened to find
only such that support a 3+ reach recommendation).
Thank you for your help.
- The Media Guru Answers(Thursday, January 07, 1999 ):
In the Guru's opinion, 3+ became a popular base level because of classic research from 1883 by a physiologist examing learning of nonsense syllables. He found 3 repetitions to be the crucial level.
Many people have come to use 3+ as a rule of thumb and others using various analyses of competition, clutter, product interest, etc have judgementally justified levels from 2+ to 9+. It is essentially a judgment and selling excercise.

I am currently analyzing a media schedule that includes consumer print, trade print and national cable. I have been
asked to pull a reach and frequency for the entire schedule. I realize that I am working with several differenct universes. I have added
the circulations and pulled the gross impressions for cable. I have added those together. Is there any formular to determan a reach and frequency?
- The Media Guru Answers(Thursday, December 24, 1998 ):
In general, different media have different audience accumulation patterns when thinking about net unduplicated audience vs gross audience.
Calculating reach from a total multimedia impressions number is not practical unless the gross rating points (impressions divided by GRPs) is so many thousands that a 95+ reach can be assumed.
Some media, in particular broadcast media, allow general estimation of reach from a table of GRP levels. Print media are more complicated.
What you really need is standardized media software for reach and frequency calculation like that which is offered by AMIC 's sister company, Telmar.

Dear Guru. Thank you for your answers - they are very
helpfull to me. My question is on "recency".
1.What groups of products best fit for "recency"
2."Recency" planning needs continuity. But it is
not evident what frequency level is needed at every
moment of such continious ad campaign. It seems
reasonable to set more frequency at the launch period
and then decrease frequency for mantainance. Also we
should take into consideration seasonality. Thus our
campaign becomes pulsing but not continious. What are
your comments? Thank you very much.
- The Media Guru Answers(Friday, December 04, 1998 ):
1- Recency seems to best fit common products that are bought regularly; in other words, a purchase is stimulated by running out of the current supply. This means food and HBA products, primarily. More "considered purchase" products, like automobiles, may not be a good fit.
Erwin Ephron, principal proponent of Recency, has commented to the Guru that about 30 reach on a weekly basis is a threshold level. This might mean 50-60 GRP depending on the media used amd target.
Part of recency theory, in relation to frequency levels and effective reach, is that after three exposures have been delivered, every subsequent exposure is supported by adequate frequency. Recency generally applies to brands with established awareness; when you raise the issue of product introductions, it is a different situation.
Seasonality is the principal exception to recency. There is no point in delivering the most recent ad exposure at a time when no purchase is likely. It is important to distinguish products with seasonal fluctuations, like deodorant, from products with very specific seasons, like barbecue charcoal.
Also consider that Recency does not mandate even levels in its continuity. The weight can be raised above the threshold when appropriate.

Guru- Can you please explain Gross Weekly reach Points (also refered to as levels)?
How are they determined? Thanks.
- The Media Guru Answers(Wednesday, December 02, 1998 ):
The Guru believes you mean "Gross Weekly Rating Points," a term often used to mean "levels." "reach" is a term referring to the net, or unduplicated, audience.
Gross Rating Points are the sum of all the ratings of all the announcements or insertions of the campaign, or the sum of all the impressions of the announcements, divided by the population for the relevant target demographic.
An "impression" is created every time an audience member is exposed to one advertisement.

We have a client who is planning to run about 450 GRPs in cable TV. The timeframe for the spots
is from 6pm - 1am and the campaign length is 10 weeks. We have 2 :30 spots in rotation (new copy for the client). If
frequency is important, what would be a good level to shoot for and what would be overkill?
- The Media Guru Answers(Friday, November 13, 1998 ):
The Guru is not sure whether you mean average frequency of exposure, as in "reach and Frequency" or the frequency per cable channel per week in your buy.
At 450 GRP over 10 weeks, you will probably run about 75 - 200 spots per week, depending on the networks used and target. 15 to 20 per network wouldn't be a bad level.
The Guru believes that some cable schedules get so heavy that the repeated commercials quickly become an annoyance to loyal viewers of content specific networks.
Four week reach / Frequency would probably be in the 30 / 6.0 range.
- Tuesday, October 06, 1998 #2073
In media jargon, what does recency planning mean?
- The Media Guru Answers(Tuesday, October 06, 1998 ):
Most simply, it's the idea that the message heard closest to the time of purchase decision is most effective. This leads to plans that optimize continuity instead of focusing on achieving a minimum level of GRP's or minimum effective reach for some affordable number of weeks.
The Guru has addressed recency often; try searching the term in the Guru Archives Search Engine.
Recency has also been a hot topic on our MediaPlanning and Award-papers e-mail discussions.

Hi Guru! We have a client who has $80-100,000 extra
budget to spend this year. The budget has to be spread
out nationally (in over 150 markets). We were offered
a full page ad with a magazine (that reaches our demo)
with a circulation of 7.6 mill. for 90M. We were also
considering running a cable schedule on only one
station since that's all we could afford. Which do you
think is the better option? In addition, we are looking
to run the first 2 weeks in December.Thanks for your
- The Media Guru Answers(Friday, October 02, 1998 ):
There really isn't enough information here to make an informed decision. For instance, a lot would depend on what media are in the base level of the plan, what your base reach and frequency are already, and what are your goals.
But let's play with it anyway: Suppose your magazine is Better Homes and Gardens, which reaches 26% of Adult Women. You would be achieving 26 reach, a frequency of 1.0 and, of course. 26 Women GRPs.
Let's suppose your cable network is Lifetime. Does your money buy 26 GRPs there? More ? Less? It might get you 13 reach and a frequency of 2.0. Which is more important to you, reach or frequency? Does the magazine or does cable offer better content as an environment for what you are selling?
You need to reduce the question to specific factors which you can evaluate.

We have a client who is interested in utilizing Network
Radio over a two-month period (January and February) to
help maximize the awareness of a new brand. Is there
any research that correlates radio TRP levels with
brand awareness levels to give us some direction on
how many points we should buy for the period without
generating too much wearout?
we should buy?
- The Media Guru Answers(Wednesday, September 23, 1998 ):
Awareness is more likely to correlate with reach/frequency than TRP's. Only those reached can be aware. The same level of TRPs might reach 40% of a target or 60% depending on the schedule.
The Guru has seen research that shows that any level below 100 TRP a week in TV allows awareness to decay.
Most research on wearout which the Guru has seen ties wearout to frequency i.e. a commerical is worn out (loses sales effectiveness) after "X" exposures. This may be expressed as the frequency in the next-to-highest quintile. I.e. the 40% most exposed to the commercial would have "X" or more exposures. 25 exposures might be the threshold level you choose. This level would occur at about 200 TRP/week for 8 weeks, which is more than the Guru would guess you would buy.
By the way, one Adult 18-49 plan with those quintiles would have a 66 reach. Another plan with the same TRP's and different schedule could have an 85 reach and just 22 exposures in the next-to-highest quintile.

I am looking for a method of calculating reach and frequency for national syndication radio vignettes.
A. Does the amount of time of the vignette matter ie, 90seconds, 120seconds etc.
B. Is there a method of adding multiple radio station figures together and averaging out these calculations accurately.
C. Is there an inexpensive source for this information on a national level.
- The Media Guru Answers(Wednesday, September 09, 1998 ):
A) Length doesn't matter in reach and frequency (unless you are dealing with a commercial long enough to experience audience turn-over during its air time).
B) In syndication, usually stations are exclusive with a given geography, so the audiences are additive nationally, or may be mean-averaged across markets.
C) Arbitron and RADAR provide such data. "Inexpensive" is a matter of opinion.

I'm new in the Advertising field. I would like to know
how to calculate the Target Market reach1+, reach2+,
abd the Average Frequency.
- The Media Guru Answers(Wednesday, September 09, 1998 ):
The answer depends upon what data you are starting with. At its most simple,
"1+" reach is the same as just saying "reach". If you know the GRPs, and the reach, then the average frequency is calculated by dividing reach into GRPs.
At bottom however, in each medium, TV, radio, print, etc. reach was actually measured at some point, rather than calculated . That is, using respondent level measurement, such as Nielsen or MRI or Simmons, actual schedules advertiser were evaluated for gross audience accumulated and the net reach accumulated, as well as how many people saw exactly one advertisement in the schedule, how many saw 2, how many saw three, and so on. As the Guru stated above, reach is defined as those who saw one or more (1+) advertisements. 2+ or 3+, etc, is determined by adding those exposed to each discreet number of ads.
Taking the results of many of these schedules as a scatter graph, a classic reach curve may be plotted. Or, by arraying GRPs and frequencies in a table, a formula equivalent to the curve can be determined statistically. This formula then becomes a "model" for calculating reaches of other schedules in similar media. Formulae for 2+, 3+ frequencies can also be calculated. There are no simple formulas for doing this. "Beta Bimodal" is one statistical function frquently used. These functions and models are usually built into large computer media planning systems like Telmar's.

I am currently pulling together information for one of
my clients on national cable advertising. I have spoken
with different network reps and have been told that they
can not provide reach, frequency, or TRP's. They have
said that they are not measured this way. Is this true?
The network reps have provided gross impressions (in
thousands). Is there a minimum threshold for this
- The Media Guru Answers(Saturday, September 05, 1998 ):
Everything which has its impressions measured in national tv has TRPs, which is merely a calculation: the division of impressions by the relevant population base, either in the cable network's coverage area or the total U.S.
Any metered measurement can produce the data for calculation of reach of schedules or the production of formulae which will allow estimation of reach.
The Guru would guess you are dealing with smaller networks whose ratings and reach would be unimpressive and therefore are not a part of the sales effort.
A 0.1 rating is the usual threshold for reporting in a printed report. There may be a requirement to earn this rating over a specified time span before even this level is reported. On the other hand, networks with ratings normally below this level are likely to be bought strictly for their content/environment, not their audience delivery.

Both we and our client agree to the recency theory. The
problem is that given the retraints of the budget,
we are only able to schedule "weekly" advertising for
about half the schedule while still achieving minimal
weekly TRP threshold levels. Right now we are wrestling
with the dilemma of how to schedule these weeks for the
first half of the year while still following the
principals of the recency theory: (1)12 weeks straight through
then a 14-week hiatus (2)6 weeks on, 14 weeks off, 6
weeks on or (3)an alternating schedule of 4 weeks on
and 4 weeks off, etc. throughout the period. Do you
have any theory on what might be the best approach to
- The Media Guru Answers(Thursday, September 03, 1998 ):
Thinking about a "threshold level" of GRP's is instinctive, but at odds with the essence of recency theory. Review other Guru answers below about recency.

Hi, I would like to know anything regarding setting the minimun level of TRP's, or minimun reach goal. We know how to set the optimun level, but there is a minimun? One point where is better not to advertise at all. Thank you.
- The Media Guru Answers(Monday, August 31, 1998 ):
Any GRPs generate some reach and frequency.
Any reach generates some consumer impact. Setting minima is a matter of judgment and logic.
If you are an adherent of the effective reach theory, you will determine what is your effective level (3+ or more) and what portion of your target you need to reach at that level, to make advertising worthwhile. This determination will tell you either how much time you can be active in advertising or across how much geography. The Guru favors 50% as the portion of target to set as minimum to reach effectively.
If you believe totally in the recency theory, any is a reasonable minimum, because each impression has its greatest chance to produce a sale this way, as it is more likely to produce unduplicated reach at any point in time. Yet, few planners can avoid feeling there should be a minimum, probably because they want to see measured sales movement for some period of time.
In either case, seasonality and purchase cycles will inform the decision.
- Monday, August 24, 1998 #2011
We are in the process of planning for a major TV client
where we have been applying the recency theory for
the past year. Because of the size of the budget we
have been limited to around 70TRPs weekly essentially
for the entire year. In Year II our client has asked
us to consider temporarily abondoning the recency
theory and to move dollars (and TRPs) out of the more
expensive buying months (April, May) to the relatively more
more inexpensive months (January, Feb)and to increase
our TRP levels accordingly. Do you have any input on
which strategy should/could have more effect on brand
performance assuming all other factors are equal
(pricing, distribution etc.)?
- The Media Guru Answers(Monday, August 24, 1998 ):
First we have to assume that the basis of recency theory is accepted.
Recency theory calls for reaching as many people as possible as close to the sale as possible. Thats's why continuity is emphasized for products with little seasonality and regular purchase cycles.
One of the essential elements of recency theory is that not all impressions or GRPs are equal, even in the same programming. You are focusing on cost per point. As you are probably aware, reach developed per GRP decreases with every added GRP in a schedule. There is therefore, a declining return on investment in reach at any point in time, which is why spreading out prospects reached produces the optimal return. The first 10 GRPs bought in a week generate more reach than the last 10 GRPs.
Hence, the added impressions bought when they are cheap produce less sales than the impressions lost from the more expensive times.
So now you have to evaluate what might be produced. Assuming you are lowering -- not eliminating --activity in higher priced periods how many more impressions, and how much more reach can you achieve in low priced times. If you cut back 10 reach points per week in July but buy 20 added reach points per week in March, perhaps the added reach can sell more than the lost reach, or perhaps not. The Guru would look for a 50% minimum trade up in added vs lost reach points to justify the change; i.e. if the plan goes down 10 reach points per week in one period, then it need to go up 15 reach points per week in the other.
- Friday, July 24, 1998 #1973
I need help! I need to know the forumla (or formulas) for figuring the reach and frequency on a television schedule. I need it to be demo / and have the following information: universe, impressions and GRPs. What else do I need and what is the magic FORUMLA! At this point we are using the cumulative impressions into the universe to figure the reach - but could that be right? I don't think so - but the reach is what I need to figure (already have GRP and freq is easy if I have reach!).
Please help - and thanks tons.
- The Media Guru Answers(Friday, July 24, 1998 ):
When you divide the accumulated impressions by the universe, your result is GRPs. There is no simple reach formula unless you already know GRPs and frequency. There are various very complicated algorithms for calculating reach for a given average rating size, known average duplication between programs used, etc. "Beta Bimodal" is one of the best known.
But today, reach calculations are done by computer, using models built from Nielsen's actual measurements of net audience reach from meter-measured schedules.
Telmar, AMIC's sister company, is the leading provider of software for such analyses.
Before computers were commonplace, media planners had tables which gave reach for various GRP levels depending on demos, dayparts and duplication. These, too, were based on average Nielsen audience accumulation reports.
- Friday, June 26, 1998 #1927
Are you aware of any published research that indicates
at about how many GRPs recognition (or even recall)
measures begin to level off?
- The Media Guru Answers(Saturday, June 27, 1998 ):
There may be many such studies, most likely available through the Advertising Research Foundation library or Newsweek
Media Research Index. However, when such single variable sudies are published, it makes it all too easy to overlook the fact that the creative carries the greater burden for your measures. Thus the perpertual questions about how many GRP = wearout.
- Thursday, June 18, 1998 #1905
Is there a threshold at which you maximize on reach (TV) at a certain weight level?
I am purchasing a high concentration of GRPs (60% in prime / 20% in news/prime access / 20% early morning/daytime/late night) in excess of 300 Ad 18-49 GRP's per week for 4 weeks. Running R&F against such a plan shows reach at 99% --- which I feel is impossible.
Isn't the threshold of maxing out on reach at 96%?
- The Media Guru Answers(Friday, June 19, 1998 ):
The typical, short term cume study gives a 96% top end. But 99% of Homes have TV so a 99 reach is theoretically possible.
Since either 96 or 99 is the result of all TV collectively, a very heavy plan is required to achieve it, especially in today's fragmented TV environment, where cable has so great a share of viewing.
For your schedule, even 96 is probably somewhat high. If your R&F system is unsophisticated, outdated or unable to adjust to the number of weeks in the schedule, that may explain the high result you are getting.

1.what is osto's model?
2.In case of an absence of duplication data for publications, how do l calculate
the effective reach using 2 or more media vehicles? in such a scenario, is it safe
to use the random theory even if multiple readership is negligible?
- The Media Guru Answers(Tuesday, June 02, 1998 ):
1) The Guru is not familiar with Osto's model. It may be specific to India, from where you are writing.
2) The Random method is a starting point. If you can find two other similar publications with measured duplication, you can use the duplication ratio from those publications. If you literally mean "effective reach," that is, reach at or above a minimum exposure level, then you need a more complex formula or a computer program like Telmar's ADplus.

1.Please, where can I find "Archives" by topic?
2.I have seen a table showing Awareness level correlat
ed to Target GRPs.Could you, please, tell me how they
estimate Awareness level?
3. I also have seen a table showing Audience engagement
in various activities when average commercial is aired.
Would you, please, tell me how the information is obtain
ed? Is it from a national panel? If yes, does this panel
also provide audience data? Thank you, Inocima.
- The Media Guru Answers(Tuesday, June 02, 1998 ):
1) The Guru Archives may be accessed from their link on the Media Guru Page. In the next few days, we will be adding a search engine to allow you to find all all past Guru answers on the topics of your choice.
2) The Guru isn't familiar with the table you have seen. Since you are writing from Brazil, it could be based on research totally unfamiliar to the Guru. The proper way for such a table to have been created would use just estimates of awareness, but actual survey results. An advertiser or agency which has conducted many awareness studies and correlated them with actual GRP's of the plans running in synchronization with the studies could create such a table.
In fact, just a few actual measurements could be the basis of a table if it is assumed that the awareness / GRP relationship follows some sort of curve as does the reach / GRP relationship. The Guru is familiar with one formula for predicting awareness based on GRP, which came from analyzing several plans and surveys. In essence, it predicted that when there was any significant starting awareness, awareness declined in any week where there were less than 100 GRP.
3) Again, Brazil's audience engagement data is not familiar to the Guru. In the U.S. such data usually comes from secondary sources such as our Simmons or MRI, which ask these questions but are primarily print audience and product usage studies.

- The Media Guru Answers(Tuesday, May 26, 1998 ):
1) The Guru doesn't judge radio effectiveness in terms of numbers of spots. If one schedule of 12 spots, for example, has an average rating of 0.5 (one-half of 1 percent of the target audience), which is common, it cannot be considered equal to another station's 12 spots with an average rating of 2.5 (also reasonable for top stations in the US). The first accumulates 6 GRPs and might reach 3% of the target, the second accumulates 30 GRPs and might reach 12-15% of the target.
So GRPs' or other audience measure are more realistic ways to determine levels. Having done this, if you determine that 100 GRPs, for example, is the correct sustaining level, then by simple arithmetic, 50% heavy-up is 150 GRPs and 100% heavy-up is 200 GRPs
2) Awareness begins to decline as soon as there is any advertising gap. Current thinking is that sales of a continuously purchased product are better supported by continuity at whatever level is affordable rather than an arbitrary minimum effective weekly level, separated by periods of inactivty. The U.S.'s Advertising Research Foundation has considerable literature on the topic and so might ESOMAR , the European Survey, Opinion and Market Research organization
3) The Guru agrees with you regarding opposite sides of a billboard. The competitive protection policies the Guru is familiar with in the U.S. only deal with advertising seen by the same audience, that is, traffic headed in the same direction. Usually there will be a certain range specified, such as "Within 500 feet" for metropolitan 8-sheet boards, which are about 5x12 feet and can be placed in dense concentration within cities.

how will media segmentation affect media planning ?
- The Media Guru Answers(Monday, May 18, 1998 ):
"Media Segmentation" is a two edged sword. Highly segmented (fragmented) media allows better targeting. But, at the same time, it works against building higher reach levels.
A clever plan will find the best compromise between these two.
The current, "recency" approach to planning can take advantage of the efficiency of reaching lower levels of target consumers on a more continuous basis.

we are in the process of recommending to a new client a media strategy
that will help him sell more olives and cucumbers (both products in
either can and glass containers). The client has a large marketshare,
about 42%. Neither this client nor competitors have ever advertised
their products. In this respect the category has been rather dormant.
What guidelines can you provide regarding a 3 year plan. Since the
company name is very well known, does it make sense, for example, to
'fortify' TV advertising with radio? Providing that radio has very good
reach, is there a synergetic effect with TV or is the money better spent
in one media?
- The Media Guru Answers(Thursday, May 14, 1998 ):
Modern thinking for such products emphasizes reach over frequency.
It is more important to have some presence at any time that a purchaser might be making a purchase decision, than to drive reach to high levels (with more frequency) over a short campaign.
One guideline tha comes from this is to make a media mix more valuable, since a secondary medium almost always adds more reach than additional investment in the base medium.
Assuming then that you can afford an acceptable minimum continuous level of TV, addding radio will be wise.
No matter your client's awareness and market share, the first entry into advertising in this category will probably change the picture.

Is there a correlation between GRP levels and awareness? If so, what GRP levels are recommended to significantly effect awareness? The category I'm looking at (long term care insurance) has low consumer awareness, and a high avoidance
- The Media Guru Answers(Monday, May 11, 1998 ):
In its simplest terms, there is a correlation. Obviously, the more GRPs delivered, the more awareness is created. Creating new awareness will take more GRPs than sustaining existing awareness.
A safe minimum guideline is to continuously reach more people than the existing level of awareness.
It is also important to remember that awareness alone doesn't make a sale. The message must be persuasive, not merely one of which the prospects are aware.

what is the correct television weight for a campaign
- The Media Guru Answers(Monday, March 30, 1998 ):
The "Correct" weight depends on many factors, there is no
one correct weight.
One way, but certainly not the only way, to calculate an
appropriate level is to follow this checklist:
- (A) How many new sales / product units, etc are
your monthly sales goal?
- (B) What percentage of the prospects who are
successfully exposed to your campaign are likley to buy what
you are selling?
- Divide (A) by (B) to determine with how many prospects
per month your advertising must effectively communicate.
- Using the reach and frequency calculating system of
your choice and your judgement of "effective levels of
communications, calculate what level of weight delivers the
desired effecively reached audience.

Two Questions: 1) I've been asked to prepare a presentation covering "Alternative Lifestyles Marketing".
When I was given the assignment I asked for a definition of "Alternative Lifestyles", but didn't get a
good answer. How might you interpret this "target"?
2) I'm seeking information on the "Optimizer" programs that have become newsworthy (in media circles)
as a result of the recent mega-million P&G AOR assignment. I've heard there are two. Who are they,
and can you describe briefly what they do (strengths & limitations)?
- The Media Guru Answers(Monday, March 16, 1998 ):
1) "Alternative Lifestyles" generally refers to
non-traditional social orientations which may become the
major influence on a person's relationships, extending to
product choices, entertainment choices, clothing styles,
etc. Most often, "alternative" seems to be used to
refer to socio-sexual distinction.
The Gay market is
probably probably most familiar of the "Alternative Lifestyles"
markets. Others might arguably be the singles market, the
mature market, punk, rapper, etc.
2) Optimizer programs are designed to build media schedules
based on detailed analysis of each possible "insertion"
(print or broadcast).
Usually the programs optimize reach within budget.
Therefore they will first select the most efficient (cost
per rating point) single insertion. Next they consider
every other single insertion, including a second use of the
first selection. The pair of insertions with the greatest
net reach per dollar becomes the next selection.
In some systems, each "best" choice is frozen as the
base upon which to build additional schedule until the
budget is exhausted. In more sophisticated systems, entire
schedules are reevaluated for best mix at each incremental
In either, it is up to the planner to set constraints on
which vehicles are to be considered, any weights or
restrictions such as using each vehicle a minimum number of
times, if used, or a maximum number of times.
Several agencies have proprietary systems. In Europe,
there are commercial systems including "Supermaximizer" and
In the U.S., the Guru believes the Telmar Optimizer is the
only commercial system available allowing TV optimization
with any available audience database (e.g. NTI, NSI, Cume

What is the recommended duration to run an initial online campaign drawing traffic to a new web site. 2 months? 3 months? Will there be message wearout? Also
should banners be changed weekly?
- The Media Guru Answers(Tuesday, March 10, 1998 ):
- Since your server log will tell you how traffic is
building, plan to run the campaign until a desired traffic
level is reached or until the growth curve flattens.
- The research seems to indicate that there is a sharp
fall-off in response after 3 exposures to a banner. So
wearout will be fairly rapid, if you place your banners on
sites with a lot of repeat visitors instead of high
turnover, or on related sites that get the same visitors.

Could you please give me your views/suggestions on the following:
1. How can you set media objectives for a banking client in a market with only two major competitors; both of whom do not have a clear-cut advertising campaign? Would a % above last years GRP levels be appropriate; in proportion to the market share desired? What other parameters should I consider?
2. Qualitatively or quantitatively, how can front page solus positions in newspapers be compared with inside pages and ear panels?
3. And lastly, how do you add TV and press GRPs; for a specific audience?
Sorry about the long query.
Thanks in advance
- The Media Guru Answers(Saturday, October 18, 1997 ):
As a rule, the Guru sets media objectives based on
marketing goals, not competitors' activity. Some
marketing goals do indeed lead one to comparsions with
competition, and awareness of competitors' plans is always
If the key marketing goal is share growth, then a
proportional increase in weight is one approach. But
consider that share, like reach, exhibits an asymptotic
curve. In other words, it can't pass 100%, so the higher it
goes, the more effort is required to "move the needle."
Consider: You first assume that "X" amount of GRP's are
required just to maintain share, on the assumption
that competitive activity doesn't vary (and that advertising
is the only variable influencing share).
Have you considered whether current share is
proportional to share of GRP weight among competitiors?
Would 50% more GRPs grow share by 50%?
No, if only because it increases the size of the total advertising
arena. Your 50% increase in GRP does not increase your
share of GRP by 50%, so calculate the right
number to increase share of GRP, if you follow that
But since there are competitors, perhaps it takes 50%
more weight to gain 25% more share?
Newspaper positions can be compared on a basis of noting,
reading, recall, etc. In each country or culture (you are
writing from India), the relative power of media and the
way consumers relate to them are different.
In the U.S., for example, a front page ad in a newspaper
would be quite unusual if not unheard of.
Contacting the U.S. Advertising Research
Foundation or ESOMAR, the European Survey, Opinion and Marketing Research organization, or
your own country's newspaper advertising association may
turn useful up research on positioning.
The Guru treats GRPs of different media as simply additive.
When there are established effectiveness factors, as some
advertisers have developed, GRPs may be accordingly
adjusted before adding, in comparing plans.
- Thursday, June 19, 1997 #1366
I have a set of urgent questions to ask of you. I have a meeting tomorrow, and need your help!
1. How is effective reach calculated?
2. reach v/s Frequency -- when should one be given priority / importance over the other?
3. Is there any way of taking creative into account while analysing competition? If yes, can a system of weights be worked out?
4. How do you reconcile to the vast difference between reach/frequency deliveries from a Peoplemeter system as opposed to the Diary system? My client refuses to accept a 4+ reach of 30% being accustomed to levels of 70% for the same plan!
Would greatly appreciate your immediate reply.
- The Media Guru Answers(Thursday, June 19, 1997 ):
1) In any schedule of several commercials, some of the
target group will see only one, some will see two, some will
see three, some will see four, some five, etc, etc.
actual measurement is based on tracking the cume of
several different advertisers schedules in a single
measurement period such as one month of the PeopleMeter.
A mathematical model that will match the measured
GRP/Frequency is calculated so that plan deliveries can be
predicted. Going more deeply into the actual measurement, it
can be determined how many people of each demographic group
were exposed to each commercial in the schedule and a model
calculated which will predict that performance for a plan.
For example, below is the typical output of a computer
models' frequency distribution, showing what percent of the
target saw exactly n commercials and what percent saw
n+. (this example is from Telmar's ADplus):
Frequency (f) Distributions
% who saw
#seen exactly at least
----- ------- -------
Target: f rch rch
P18-49 --- ----- -----
0 69.1 100.0
1 11.5 30.9
2 6.0 19.3
3 3.7 13.4
4 2.6 9.6
5 1.8 7.1
6 1.3 5.2
7 1.0 3.9
8 0.7 2.9
9 0.6 2.2
10+ 1.6 1.6
20+ 0.0 0.0
2) reach vs Frequency: The determination of emphasis here
can be a complicated analysis making up the greater part of
a plan's documentation, under the heading of
"communications strategy." A commercial so powerful that
it's sell is overwhelming in one exposure might take the
"Let's buy one spot in the Superbowl" route as did the
Macintosh computer with the classic "1984" execution.
In more competitive situations, competitors' levels are
taken into account, clutter in the media of choice, copy
quality, etc. Obviously a balance must eventually be struck
between reach and frequency based on judging all these
3) There are several ways to take creative into account
while setting up reach vs frequency goals;
complexity or simplicity of the message
The number of
commercial in the pool
how close your commercial is to
the established "wear-out" level
The balance of :30 to
etc, etc. can all be assigned factors and totalled or
averaged to give a reach vs frequency emphasis factor
similar exercise can also set effective frequency
4) There should not be "vast"
differences between effective reaches based on people meter
and diary systems if schedule GRP and other aspects are the
same. 5 or 10% would be the range the Guru would
A plan with a 70 reach at the 4+ level would be
delivering in the range of 98% total reach. It sounds
as if your client may be confusing a plan with 70 reach and
an average frequency of 4 with 70 at an
effective frequency of 4. Or perhaps
confusing 4-week reach with a long term cume?
- Friday, June 13, 1997 #1365
Could you please give your opinion on what can be viewed as a recommended level of GRP, frequency and effective frequency for a highly competitive advertising category on TV. As an example we can take a carbonated soft drinks' category. What should be the planning guidelines? When and why we should use flighting (pulsing) or what is the rationale for a continous campaign. Additionally to TV which other media should we use and why?
Thank you in advance,
- The Media Guru Answers(Friday, June 13, 1997 ):
You are actually asking for the complete Objectives,
Strategies and communications tactics of a full scale media
plan, without offering enough background.
Nevertheless, here are some considerations:
One theory of competitive media planning calls for
delivering a minimum of 10% more impressions than the key
competitor, in head to head media. This assures beating the
competition in GRP, reach and effective reach.
Budget is a consideration. If there is not enough money to
compete as above nationally, then selecting geography where
the delivery advantage can be maintained should allow you
to beat the competition, bit by bit, until you can afford
When there are time-sensitive promotional issues, then
pulsing can be an effective way to deliver more impressions
over the crucial period. Recent media theory has emphasized
the benefits of continuity, because "the impression
delivered closest to the purchase decision is the most
effective impression." In the soft drink category, where
purchase decisions are constant, continuity may be
generally preferable to pulsing.
In other, highly competitive, seasonal categories
pulsing may be needed.
As far as recommending other media, that calls for more information, but
please look at the Guru's Media Advertising Strenghths

Is there any model that relates advertisign awareness
or brand awareness with media weight level? If there
is no measurable coverage of the media, say computer
magazine, what can we base our judgement on.
- The Media Guru Answers(Monday, May 12, 1997 ):
When there are published studies of this sort, the Guru can
usually find them in the Advertising Research
Foundation Library or in the Newsweek
Media Research Index
There is, no doubt, a great volume of studies which are
held proprietarily by advertisers.
There was a model the Guru once used, based on certain
Agencies' many tests, which roughly assumed ad awareness
would equal 91% of the existing awareness plus 3% of
the previous week's GRPs (gross audience coverage).
It should be obvious that this model works best for brands
with little or no going-in awareness and also dictates
that anything less than 100 GRP per week leads to declining
awareness for brands with awareness above 35%
Media coverage can be estimated for print media:
circulation is usually known; readers-per-copy and
composition can be approximated by comparison to similar
It should also be kept in mind that awareness is not a factor of media alone, but depends, to great extent on creative.

I am trying figure out the best way to calculate reach & frequency for the following:
4 consecutive weeks (250 TRP's per week)
Then scaling back and running 175 TRP's per week - Every other week for the following 8 weeks.
How do you calculate R&F when your schedule runs on an every other week basis?
- The Media Guru Answers(Monday, February 24, 1997 ):
There is no basis for believing that an alternate week schedule of 700 total points (175 per week for 4 of 8 weeks) cumes to a different total than 87.5 GRP per week for 8 weeks, as long as the scedules are otherwise identical in numbers of different announcements, and numbers of different episodes of the same programs.
It is true that if the schedules per week of activity were solarge as to exhaust reach potentials, the answer might bedifferent, but this is far below such levels
So the total schedule of the first four weeks at 250, plus the 4alternating weeks can be calculated as if there were lower levelconsecutive weeks.
- Monday, February 17, 1997 #1045
I am interested in obtaining research that explores effective consumer promotion television weight levels. A typical consumer promotion window may be 2 - 3 weeks. Most consumer promotions are planned in the neighbourhood of 300 GRPs / week. Is there any research that has measured effective levels. I am trying to identifity an optimal level, a level (or range) below which response/sales suffer and/or above which response/sales do not substanitially increase.Goal- avoid spending too little or too much against a given promotion.
- The Media Guru Answers(Friday, February 21, 1997 ):
There are so many variable beyond GRP weight that the Guru doubts you will find simple answers.
Just a few are copy length, daypart mix, competitive arena, product interest, and commercial quality and wear-out status. Further, the Guru thinks that effective reach / frequency is a more useful quantitaive standard than pure GRP.
Two places to look for relevant research would be Newsweek Media Research Index or Advertising Research Foundation
- Tuesday, February 04, 1997 #1056
What is the best way to determine effective reach? Any availabale research?
- The Media Guru Answers(Sunday, February 09, 1997 ):
Effective reach refers to the concept that people exposed to advertising are only exposedd "effectively' beginning witha certian number of repetitions of the message.
originally, 3 tiems was the standard, based on the work of Ebinghaus in the 1880's, who tested learning of nonsense syllables.
Today logic and experience tells us that many factors determine the number of repetions necessary before recognition and understanding of a message will turn into motivation to buy.
The power of the creative, the clutter of the media used, the competitive environment, the interest of the consumer in the category, whether it is an impulse item otr considerd purchase are just a few of the 20+ factors commonly used to judge whether the effective level mustbe set at 3, 4, 6 or more.

Is there a standard industry statistic on using a 1-800 number in tv and radio spots and what the response levelpercentage is? If it is a percentage, is it a percentageof the number of times the spot ran or a percentage relatedto the target audience?
- The Media Guru Answers(Tuesday, December 03, 1996 ):
There are a number ov variables in this kind of direct response, several of which are more important than the ones youmention.
Is the 800 number purely informational or a sales responsevehicle?
What is the product, how unique, how interesting?
What is the product's price?
How good is the commercial?
The Guru believes there are almost mystical aspects to Direct response. Sometimes spots with smaller audience seem toproduce more response than others with larger audience, whenthere are no apparent difference in target composition orprogramming "fit".
Sometimes one station seems to outperform a similar station whenimpressions, spots and programming appear identical.
Overall, 2% of people reached, is generally considered anoutstanding response rate.

I am a consultant to a TV station. Recently most agencies have adopted one or another Media Planning software. We have tried to undersatand what type of optimizers they have and what effect in their decisions may have. For example one that uses integer programming seems to benefit high GRP programmes while others low cost and low audiences. How does the type of optimizer influence the plan? Thank you
- The Media Guru Answers(Wednesday, October 23, 1996 ):
Optimizers must be set to Optimize something. It may be pure reach, reach at a given level of frequency, reach within a specific budget,etc. Usually some form of reach is in the goal, because other considerations like cpm or GRPs are simple arithmetic, while reach involves more complex computer models.
The reach models must be based on some measurement of "actual" schedules to be worth anything at all. If each optimizer is merely based on some programmer's opinion of how audience accumulates, there is no way to predict results without owning a copy of the program.
When reach within budget is the issue, it is possible forlow cost/low rated programs to be preferred if theydeliver so much more gross audience that even at low rates of net accumulation, the total reach can be more than quicker 'cuming. high-rated schedules.

I was wondering what the effective levels of reach &frequency for a new product launch would be, as well as an adequate budget?
- The Media Guru Answers(Friday, October 11, 1996 ):
Determining the effective levels and desired geographic scope will determine adequate budget.
There are no absolutes in effective levels for intros or any other purpose.
Issues to consider include:
- Competition; how many, spending how much
- Clutter in the media to be used
- Typical levels of frequency in the media used
- Complexity of your message
- Interest in your product type - e.g. insurance vs sports cars
- Ability of the target consumer to digest information
- and others which may be specific to your own situation.
Generally, you want to reach the majority of your target at the determined effective level.

What is the most rapidly growing advertising medium?
- The Media Guru Answers(Monday, September 16, 1996 ):
According to a recent Ad Age report, the web, though still the smallest, grew about 50% from first quarter to second quarter this year. That surely is fastest. In the not too distant future, some sort of stable level will surely be reached, and growth will be merely inflationary as with most other media. On the other hand, technology being what it is, there may be a new internet or other similar breakthrough before that happens. Who would have predicted today's WWW importance just two years ago?

Dear Guru,We are planning a campaign in the market, where no consistent media research data is available. What we have at the moment is following:1. 2 heavy competitors (one is our client)2. The competitor is running a campaign in the key city of the region using 3 local channels with a combined monthly reach of 93% of the city and the surrounding area, which equals 12.5% of the regions' population. The competitor is spending ca. USD 90K per month.3. We have the objective of running a regional rather than local campaign and, at the same time, outvoice the competitor by 30%.4. To our choice are 3 regional channels with a combined reach of 40.7% in the regionQuestion: what budgert should we be looking at on a monthly basis, given that the average ratio of the local rate card to regional one is 1:1.5?
Sorry for asking for a piece of alchemy and thank you in advance,
- The Media Guru Answers(Friday, August 30, 1996 ):
The simplest conceptual answer is to spend 30% more than the competitor in the key city: USD117 This way you outspend him where he's active and meet the 30%+ goal. Otherwise, assuming the regional buy includes the key city, your budget is still 117, with some in regional media and some in the more efficient key city media, so that you have at least a 10% edge in key city impressions.
If the rate card is telling you that a $150 spot buys thewhole region at the same rating that $100 buys the key city's 12.5% of the region (if the Guru followed your data correctly), then 1.3 x 1.5 x 90, or 175.5 is the budget to deliver 30% more impressions in the key city and an equal level across the region.

My telecommunications client is planning a multimedia (TV, newspaper, radio) launch in Chicago this fall, hoping the phone will ring off the hook. Is there a way to predict response levels per medium (or in total?) for the client to effectively staff its phone lines? I have total population, target population, reach & frequency levels (for TV - a 6 week flight; for radio a different 6 week flight; print used in both flights). The kicker is: this is not a direct - response spot (of course, an 800# will be included, but generally, it's an image builder). I also know that it will depend greatly on many things creatively (length of time the 800# is on the screen, is it a pnemonic number, is there an offer, etc). I'm thinking if there is an easy answer to this, I wouldn't have a job.
- The Media Guru Answers(Wednesday, July 24, 1996 ):
The safe answer is to contract an "inbound telemarketing"service which is large enough to expand or contract around your actual traffic. Depending on the offer and strength of copy, calls could equal .01% to 5.0% or more of persons reached. Using a service the first time out, especially if you're not specifically setting up a DR business, will give you benchmarks for the future.

I am convinced that with a limited budget it is necessary to reach "effective" reach levels at a given period of time rathe than spread thos dollars throughout the year to achieve low levels but high coninuity. I am working in the Automotive field. Please help me. I need specific documented research studies on effective reach!!!
- The Media Guru Answers(Monday, July 08, 1996 ):
It isn't clear what your query is. Many people continue to feel as you do. In recent years, many others have espoused the "propinquity" theory which advocates continuous low levels, based on the idea that the single exposure closest to a purchase occasion is the most effective.
There has been considerable trade publication comment on the matter, most often by Erwin Ephron, probably the leading proponent of propinquity. A recent Advertising Research Foundation workshop devoted considerable attention to this issue, and the proceeding of that conference should be available from the ARF. There have been opposing positions, in agreement with yours, published as well, one of the earliest by Abbott Wool in Media Week shortly after Ephron's first publication of the theory.
The Guru has discussed this before, so using your browser's "find" function to scan this page and the Guru archives will provide additional material.
Surely the most archetypical exception to continuity is for the highly seasonal product, as automotive products may be.

Dear Guru,I have two questions which you might have heard before.
a)I do know that a :15s commercial on TV cost between 50% to 75% of a :30s depending on market etc. Is there any studies that show what the benefit of either length is (if any) in terms of reach, frequency, effectiveness, memorability, etc.
b)I have seen studies praising the advantage of multiple media usage above single media; in other words using TV and radio instead of just TV. Can you elaborate on that and update with new info about this topic. Reason being a client who would like to slash the budget down to just using TV for campaigns. I however feel that there is an added benefit in using multiple media.Please respond by Monday if you can.Thanks.
- The Media Guru Answers(Sunday, May 19, 1996 ):
a) There is is no difference in reach and frequency between a :15 and a :30. In the same time period, they have the same audience, within the tolerances of research measurement.
On the other hand, a schedule using :15's in place of some or all the :30's will provide more reach and frequency, because it has more announcements, hence more GRP, etc, for the same budget.
When :15's started to become popular several years ago, there was considerable research regarding effectiveness versus :30's. The general findings were that :15's had about 70 - 75% of the recall of a :30. At the time, :15's were typically a network option priced at 50% of :30's so the trade off of price vs effectiveness seemed favorable.
b) Multi-media plans chief benefit is in reach development, though the effects of the added reach have ripples in many directions.
Adding a new medium adds more reach than adding weight in the same medium: There are more likely to be different people in the audience of a different medium, over a given period of time. This applies to effective reach as well.
There are a variety of philosophical approaches to taking advantage of this.
One approach says to build reach up to a minimum effective level in the primary medium first, before adding the next medium. Another says build the first medium to the point where the reach curve flattens, then add the next medium to resume reach growth.
A newer, different line of thought, the "recency" theory, de-emphasizes reach in favor of delivering messages to the consumer closest to the point of making a purchas decison. This argues for continuity, to reach more people at all times rather than highest levels in sporadic flights. Again, multi-media will produce more reach, but other theories of minimum weekly levels may effect scheduling, ie radio bought to a minimum of 12x weekly when active.
Judgements must also be made regarding whether TV and radio is perceived as the same message by the consumer. Of course, this same judgement must be applied to different executions in the commercial pool of each individual medium as well.

I'm working on a presentation on how media planning professionals go about determining a media mix, and how a percent of budget is allocated to each medium being used. It's a general presentation for a client who is not very familiar with media planning terminology or methods. So far my sources for info include a couple of similar documents that I and others that I work with have written in the past, and the media planning textbook (by Scissors). Do you know of any other RECENT sources of info, points-of-view, articles on this topic? Or have you answered a similar question recently?

Marketing Goals ---> Marketing Strategies ---> Media Goals ---> Media Strategies ---> Media Tactics, etc.
A very simple example:
A marketing goal of increasing the number of users of product X might lead to a strategy of converting users of competitive brand Y.
The media goal might then be to optimize reach at effective levels of frequency among a demographic group matched to current users of brand Y.
The media strategy to achieve this might then be built by examining various media mixes to determine which produce the best balance of effective reach for the budget, within the creative limitations.
Of course this is just one possible marketing goal, one possible strategy that might emerge.
There are many ways to set reach goals, to set minimum effective levels or decide to apply the recent "proximity" or "recency" theory of exposure.
In short, one doesn't decide on percents of media and see how it turns out, one decides which media will best answer the marketing and media strategies. Often, some creative decisons have precedence: if TV is designated as the "primary medium" because of communications ability, need to demonstrate, etc, then the strategy migh dictate putting all money into TV "until the effective reach curve is exhausted."
There are infinite ways to express and measure goals and their achievment. Some standard media planning software, such as Telmar's Media Maestro, and Hispanic Media Maestro, allow easy examination of various mixes, instantly showing how reach/frequency/effective reach change as budget or schedules are shifted between media by the planner.

I am buying a radio schedule (100 GRPs/wk for A25-54) in a market that is approximately 28% black. The urban station in this market is relatively efficient, but is by no means a "must buy". In fact, there are about 10 stations with 9/10 of a rating point of each other (AQH rtg, M-F 6a-7p). This urban station claims that I must have at least one urban station on every buy or I will miss 28% of the market. I disagree. When buying so few points a week, I do not have the budget to buy as many stations as I like. A better use of the money would be to cover the various age cells in this broad demo and try to balance the male/female reach. My question is, What is your opinion on this subject? Is an urban station a "must buy" in this market any more than a country, rock, or news/talk station?
- The Media Guru Answers(Friday, March 22, 1996 ):
There are several levels at which this question can be considered:
The essence is determining the true value of that station: "should you buy it", not "must you buy it"
- If you ignored the fact that this is an urban station would you buy it, based on the general parameters of the buy? Rating/efficiency/rank, etc?
Are you having a negative reaction to being told you must do it?
Do you really miss 28% of the market just by not buying that station? To what reach level are you buying? At 100 GRP / week you're not likely to reach more than 72% of the target in a typical 4 weeks, anyway. So if the station is the onlyone reaching its market segment, how much does it matter if that segementis the 28% you miss rather than any ther 28% of the market.
Is that station is the only one reaching its segment? It is likely that several other stations in a market with that high penetration of Black population also reach that audience, but perhaps with a lower audience composition. Check the schedule you will buy to see how its African-American audience reach compares to its general market reach. Perhaps it's comparable even without that station.
On the other hand, if that segemnt is important, reaching it in a culturally relevant program environment can substantially enhance selling opportunity.
Examine the product usage data about your client according to Simmons/MRI/Scarborough/MMR, etc. Perhaps the African-American consumer is far more valuable to your client as a prospective customer than is the general market, and that Urban station, with its good efficiency, is the first one you should buy, even if it does sell aggressively.

Can you fill me in on "recency"? Sounds like a complicated way to say low media weight, long duration? Is this correct? If so, can it work with a small budget?
- The Media Guru Answers(Monday, March 18, 1996 ):
Recency does amount to lower weight and longer duration, but allows for more complex discussion. It is a theory which works in opposition to "effective reach." Effective reach is based on the fact that 3, or some other minimum number of exposures to advertising, is necessary for the advertising to be digested, understood and begin to effect consumer behavior.
Recency posits that an exposure close to the moment of purchase decision is the most effective, therefore maintaining a constant presence of messages is most likely to catch the prospect at the crucial moment.
Obviously, even within the recency model, the more exposure provided at any given point in time the better the chance of catching a consumer at the critical time. Recency argues for continuity, not for low levels, though it is often used to justify low levels.
Recognizing that truly seasonal purchases call for different scheduling than regularly cyclical purchases, the concept says that if a given number of impressions are affordable, all else being equal, those impression will generate more sales when spread consistently rather that concentrated into flights at a presumed "effective" level.

I would like to know if in United State exist any research, about outdoor reaching people. If exist, could you give me an explanation, and any address to try to get more information. How an outdoor campaign is evaluated in U.S.? How many people reach, this kind of study. Thank you in advance
- The Media Guru Answers(Friday, February 02, 1996 ):
There are measurement sytems and standards for outdoor media in the U.S. Outdoor (more generally called Out-of-Home media, to include buses, bus shelters, subways, etc) is measured in GRPs as are other media. Outdoor GRP's are measured on a per-day basis, while broadcast media are more often thought of on a per-week basis.
Therefore if one buys 100 Adult 18+ GRPs of outdoor posters, the daily audience exposures (circulation) are equal to the Adult 18+ population of the market area. So a 100 GRP buy is about 3000 GRP per month (100GRP per day x 30 days.
Typical reach systems will report that this level of outdoor delivers a reach in the 90% range with over 30 frequency. You may buy 50 GRP or 25 GRP, of course. Even at these levels reach is typically 80+.
Years ago we talked of "100 showing" or "50 showing" which was sometimes the plant operators rough estimate of 100 or 50 GRP and sometimes just a pricing basis.
Outdoor sales companies, such as Gannett (212) 297-6413 can provide scehdule-specific reach analyses.

what is the difference between general media and direct response television media? and would I ever recommend to my client DRTV as an inexpensive way of getting exposure?
- The Media Guru Answers(Friday, February 02, 1996 ):
General TV and DRTV are different in the way they are purchased and in key aspects of the copy used. To qualify for DRTV, the copy usually must be selling something through an 800 telephone number. Mail is also possible, but the immediate nature of telephone response is preferable (900 number ads are typically under a different rate structure).
DRTV rates are usually based on half of the going rate for the time period. The concept of "going rate" is hard to pin down with any certainty, unless you are buying the same schedule at the same time as "general media." These half price schedules are typically in remnant time or relatively undesirable times late at night or early in the morning or weekends. They are also instantly preemptible. You can't rely on delivering a schedule of "50 GRP per week in prime and 75 GRP per week in early fringe" through DRTV.
General TV schedules are used to build awareness through planned levels of reach and frequency or timely impressions delivery during specific promitions or campaigns DRTV schedules are opportunistic buys, with each airing anticipated to generate a certain quata of responses for a product ready to sell at all times without specific timing issues.. DRTV advertisers often track resonse minute by minute to associate each call with the specific commercial airing responsible. This is in clear contrast with the awarenes building aspect of general media.
When your client measures "exposure" in reach or effective reach terms than DRTV is not an efficient way to get exposure. Those remnant timeslots are not reach builders.
A DRTV advertiser is generally selling something worth the investment in inbound telemarketing expenses for each 800 number order, and assuming a certain minimum of orders per airing. (You cant make money if a $5 an hour operator has to spend 10 minutes taking address, size, flavor and credit card info to sell a $2 item, unless you add $3 shipping and handling). This means it doesn't work for toothpaste, floor wax, soap or cookies, unless you're selling the $29 bag-o-groceries special.

Do you have any information about "Wear-out" of TVCs?
- The Media Guru Answers(Monday, November 06, 1995 ):
The first thing to know about wear-out is that there are no absolutes. Different people mean different things by "wear-out" There are numerous ways to set a standard for wear out and numerous ways to measure a commercial's approach to that standard. The simplest, as stated by one of the industry's great researchers is, "a commercial is worn out when the client asks about wear out." Realistically, a practical definition of wear out is when the commercial no longer stimulates additional sales. However, it's rare that any commercial is tracked closely enough to determine that point, and the trick is to *predict* that point. Commercials differ in their quality, impact, and memorability, as well as in the clutter and audience duplication of the schedules used to air them. A commercial that's one of a pool of three closely related commercials for a brand might wear out at a different point in time than one that's one of three dissimilar executions. A commercial airing repeatedly in a single daypart wears out before one in a broad rotation. The audience target and its media habits will also have an impact. Once the wear out level is determined base on the above, then it needs to be associated with a media measurement. Measurement might vary from "when the top quintile is exposed x number of times" to "when effective reach is x% over xx weeks" to "when the commercial has accumulated xxxx TRPs." Bottom line, the answer is a commercial is worn out when it stops selling. How to determine this is a question of judgement and specific research.
