Daily and monthly cume (which in most cases is showing up as larger than measured by diaries) is becoming the important measure.
First off, bravo to Dick Skinner. Great post. "Shares" generally are viewed by programmers as their report card. "Ratings" are what the sales folks use to develop their CPMs for advertisers. Thanks for providing some clarity and hopefully a little knowledge take away for many of the folks who are not in our business who read and post here.
I also, believe, SFStatic, you're mistaken. In the year or so I've been working in PPM markets, I've yet to run into anyone from the ad world (station side or client side) who thinks cume is now the gold standard. The larger cumes are truly impressive. But, the fact is, while cumes have dramatically increased, the vast majority of the increase are from people who are extremely light (P3 and lower) listeners who contribute very little to the share of the station. While cume truly shows the "circulation" of a station, it's not a very good indication of how many people might actually hear your ad. That's what the advertiser is interested in. The age old adage rings true and at a recent ARB PPM seminar, they even acknowledged it: in round numbers,
25% of your listeners give you 75% of your ratings (share/rating, not cume) This is one reason just a few PPM devices can truly change a stations' performance. I also know of no programming types (again that I personally know of) who are compensated on increasing the cume of the station. It's all based on SHARE or SHARE RANK in specific target demos based on the station. (That is of course, if you are lucky enough to receive some kind of comp based on ratings at all....whether air talent or programmer).
Dick Skinner, I'd love to hear your thoughts...
