Are you aware there is a quote function (looks like a cartoon speech balloon with lines across it)?
No, thanks, good to know.
Maybe Wilmington is not interested in paying more for more accurate numbers. Wilmington does diaries only twice a year, not four times a year like most 51-100 markets. They do data collection in the spring and fall survey periods, not in winter and summer. PPM measurements are continuous. If you follow the numbers for Philly, you'll notice that numbers can vary markedly in different quarters.
So they would have to pay more and would not generate additional revenue for the local stations so why spent the money? As I said earlier, I'm assuming that inside the book they now buy, probably does have those Philly stations listed so they now see where the rest of the Wilmington radio audience is, so why pay more for essentially the same info. It's simple dollars and cents for the Wilmington stations. They'd gain nothing so why bother?
I'd like to see PPM numbers, but if Arbitron is only going to show us in the 12+ just the Wilmington book subscribers even with the PPM folks like you and still learn nothing new either and if what I wrote in the previous paragraph is true the local station's won't benefit, so what's the point?
