Cumulus just divested NYC where they did not have a cluster capable of competing with the other big players in the market. It raised a lot more cash than they could have gotten out of the market by continuing to operate there. Ditto their sale of a couple of orphan stations in the LA market. They swapped stations with Connoisseur in a deal that strengthened the position of both groups in mid-sized markets.
The Buffalo market has been rebuilding a group stripped by the Dickey regime. It's a strong group with good numbers that has more than paid its way in the company. It's also fits the market profile that they like - not too small, and a dominant demographic position that they can sell. In radio, you never say never, but unless somebody comes along offering stupid money to get into the Buffalo market, they're not likely to sell as long as OTA radio is viable. I don't anticipate anybody will come along offering stupid money to a market which overall provides stable income but shows no tendency toward growth.
