Something I've been saying all along. For those stations looking for the younger demo (In Providence Hot, BRU & to a lesser extent HJY) 18-34 is really the first numbers I always looked at for being "real numbers". For most of the stations in town 25-54 is where the $$ is and always has been. Looking at it-right in the wheelhouse of Pro-FM, Coast, HJY, Lite, CTK, Pro-AM, EEI, HJJ, B's target demos. While it is true that B, HJJ & Pro-AM would look a little bit toward the older end of the demo and above, it is that small chunk in which everyone is fighting for.
As I said, while the elimination of those diaries hurt WPRO-AM, it also hurt the market as a whole as those 6 diaries might actually have been sent to other households, which would have had different affect on other stations' ratings, especially seeing as it was supposedly 25-34 year old distribution.
