Since buyers don't use cume...Not everything of "value" is associated with money. That may be a concept difficult for some to grasp - but let's take it back to what started the entire discussion -
In Los Angeles, Audacy's spoken word station KNX, out cumes ALL spoken word stations in the market combined. In your view "nobody looks at 12+ cume" because there is no value to it. Such broad, declarative statements should be made with great caution. Seriously.
Back in the 70's, groups like Westinghouse tried to sell "reach and frequency" which involved looking at cume and AQH persons and getting a length of listening which was used to show that long-listening stations needed fewer spots to reach more of the total cume.
Westinghouse even produced a reach and frequency slide rule which was widely distributed. No end result, though, as cume does not tell advertisers how many people heard each ad.
Agencies did not buy into R&F, and when the PPM arrived we did not even get an effective way to derive reach and frequency in that service.
And, in 25-54 KNX is 18th in cume. It beats KFI and KLAC and the other talk and sports stations, but it is still 18th overall. It averages about 20th in AQH persons, just ahead of the nearly-dead KROQ.
And ad buyers don't have a buy category for "spoken word", although they do have a category and often separate budgets for sports.
But it is not in the ears of buyers. "Cume" is not a salable quality for radio.You see no value, but Audacy certainly does. That talking point is 100% on the lips of every single seller in the organization.
Radio does not sell cume because, historically, buyers looked at rating (not share). Now, there is a large trend towards buying impressions, which is AQH persons.
AQH persons allows cross media comparisons with new media. Cume is not a new media metric.
