Some interesting ideas above:
AM is not the only reason WIP has been slipping a bit. OK, I think CBS, to some extent also recognized that. Point taken about some of the programs that stay though. It's perhaps not geared toward the younger male audience of which they'd like to have a bigger piece.
In a year (or two) the rock could be back. I don't see that ever happening. The limited, current WYSP audience will fragment into the three other rock stations, Sirius/XM, and internet radio. At best, a fraction of that would be recovered. Even FreeFM managed to keep enough of a rock connection to allow a U-turn. There's no way to do that with WIP-FM. I think WYSP has about as much chance of returning as WJJZ, 96.5 the Point, or US-1 Country. And I am/was a WYSP music listener.
Instead of dwelling on the past, let's look ahead at other stations on the same bubble as WYSP was a few months ago. Where does Wired go in a year, or Ben, or Mix?
