Media Guru: Calcuating Combined Reach of 3+ Media
Media Guru Question:
Hi Guru, I know that the formula for calculating combined reach of two media is (a+b)-((.axb). Please how do we calculate when the media that are used are more than 2? Say they there are three or four media used in a plan, how do we calculate the combined reach for the three or four media? thanks.
- Each medium is added to the combination in the same way. In other words, the first combination becomes your new “a” and the new medium is a new “b.” This can continue for as many media as necessary. Just to be clear, the two media formula should be stated as (a+b)-(axb)
Media Guru Speaks: Changing Radio Formats
Media Guru Question:
What’s the history on how a radio format switch affects other stations in the market?
Media Guru Answers:
In general, naturally, other stations in the new format feel increased competition, and stations in the abandoned format feel lessened competition.
A new format unlike any other will have less predictable results.
If a station enters a format and does something so unique and appealing that it builds new interst in that format, others in that format may benefit.
To understand better, identify cases where this has happened and track the actual reults in Arbitron.
Media Guru Answers: “Is there a standard CPP for National Networks?”
There are averages, not “standards.” Visit SQAD for resources.
Media Guru Q & A: Calculating Average CPP
Media Guru Question:
Is it possible to Calculate average of cpp for a country during one year? how? can we calculate it by Media monitoring ?
Media Guru Answer:
If the country has a source measuring spending and GRP, as we have here with CMR (Competitive Media Reports) and Nielsen Monitor+ or a CPP projecting / reviewing system like SQAD, then one can readily estimate annual average CPP.
Media monitoring, on the other hand, is a system the Guru understands as a reporting of advertising occasions, so even if GRP are included, you won’t get to CPP.
Media Guru Q & A: Unweighted or Weighted Audience Measure?
- Media Guru Question:
Dear Guru – I have a question about calculating the average rating per spot of a TV campaign which includes spots of different lengths (I work for an International media owner based in London). I have always been told that reach and frequency are always calculated using the un-weighted numbers. However, is this also the case when calculating the average rating per spot? Ie. is the calculation “unweighted GRPs / no. of spots” or “weighted GRPs / no. of spots”. Thanks a lot!
-
Reach and rating are calculated using unweighted numbers.Weighting for unit length is a technique for comparing values, but not an actual audience measure.

Media Guru Q & A: When is Network More Efficient Than Spot?
Media Guru Question: At what point does it become more efficient to buy Network TV versus Spot TV? Is there a number of markets or CPPS?
Media Guru Answer: The answer varies by demographic, daypart, whether you’re counting markets from the top down and how efficient your network vs spot buyers are. The approach is to use SQAD or whatever your local CPP records source and add market CPPs until the equal your national CPP.
The break even could come around 50% – 75% US.
