http://www.radioandrecords.com/Subscribers/ratings/homepage.htmI looked for WLBI (AAR New York) and they still have it listed as "ethnic" - Radio & Records will only give 12+ numbers for free - the numbers AAR are interested in are 18-34 & 25-54. Not that the 12+ numbers aren't important - but in the eyes of advertisers, it's 25-54 group who has the money to spend
It is my opinion that any station that might be considering AAR will be waiting for a few books to come out - Arbitron comes out every three months, with trends coming out in-between.
Hold off on your letters - if positive numbers continue for AAR - you'll have more amunition. But these guys in radio are always looking at numbers and my guess is...if they have AM stations that aren't doing so well - they may be waiting and watching how AAR is doing.
Switching formats is a big decission - not to mention that a new ad campaign would have to accompany a format switch (do they have the budget to do that?)
