CBS-FM's not going away, not now, probably not ever. It finishes in the top 5 in the NYC market in cume, AQH 12+ and AQH 25-54. It has TSL numbers to die for, which further help it to that nice healthy 5 AQH share and third place overall. It's arguably the strongest station ratings-wise in the entire coast-to-coast CBS station portfolio, rivalled only by WINS, or maybe WBZ, in that department.
Neither is Fresh going away anytime soon. It's a growing station with a cume that's also in the top 5 12+ in the latest NYC Arbitron PPM reports. It has further to go in 12+ AQH, turning in an improving but still less-than-optimum 2.7. Clearly they need to work on boosting TSL in order to get an AQH that matches the strength of the cume. But that's not too hard a task, actually. A few tweaks to playlist, personality presentation and formatics can do wonders without any major format surgery.
K-Rock, on the other hand, is at 1.5 and falling, turning in the second-worst performance of any of the full-market coverage commercial FMs in NYC (beating only the hopeless WRXP). If any station in the CBS cluster is a candidate for a format transplant it's 92.3. But you have to wonder if going head to head with Z100 will get them what they really want, or just cannibalize audience away from Fresh without getting them the overall traction in the market they need. They might be better off to wait out the end of Howard's contract with Sirius/XM, bring him in while moving O&A to their natural afternoon daypart, and revive the FreeFM concept with the key parts for a successful FM talk franchise finally in place on one single station. Or else try the one thing that'll guarantee them a 3 share, high cume and the love of suburban women and 35-54 men (the soccer moms and NASCAR dads)--a personality-driven modern country station. MIght be time to challenge the conventional wisdom about what ad agencies will buy--IMHO they'll now buy anything that draws real numbers.
