If Clear Channel is the buyer, the purchase can partially be seen as an insurance policy that its Premier talkers will be carried on a good signal in Market-One no matter what big rival Cumulus decides to do.
That probably makes WOR worth more to Clear Channel than to any other potential buyer. CC is maxed out on the FM side in NYC, and the other top AM signals are owned by its biggest rivals CBS and Cumulus, which are not likely to sell them any time soon.
CC can put Beck back on in NYC and pick up some revenue doing that, and WOR already carries Premier's Coast-to-Coast, and may be paying to have it there. Those payments would go into CC's pockets after a sale too.
Ultimately, CC's main reason for the purchase is NYC air-time insurance for its syndicated products, and WOR will likely carry as many as possible. What CC does in drivetime may be more interesting.
Rights to the Hannity show are shared by Cumulus and Clear Channel. IIRC, Cumulus originates the show in its studios and has the rights to it on all the affiliates that it owns, while Clear Channel has the rights to it for all non-Cumulus stations.
If this Clear-WOR thing happens, there likely will be interesting legal negotiations the next time Hannity's contract comes up.
On the other hand, Cumulus has been making noises about wanting to keep its programming and all revenue in-house. So, WABC may wind up as the station that gets more local programming, but Huckabee and Geraldo are both syndicated Cumulus, so the end result may be that New Yorkers have two big talk stations filled with syndicated talk shows, one all Clear Channel, and the other all Cumulus.
And in the short-term, some shows will be switching sides when their contracts run out. Limbaugh will go to WOR from WABC, and Huckabee will go to WABC from WOR.
Overall, the picture does suggest the rearranging of the deck chairs on the sinking Titanic of AM talk radio, but, hopefully, some new energy, and interest, will come to the format in NYC if all this rearranging does come to pass.
