Saw this on Radio-Info's site:

The station wasn't around here (Charlotte, NC), nonetheless it was a conservative talker that decided to go off the air completely versus changing format.

Well gee, I thought those kind of stations NEVER went out of business, just the liberal ones. Oh wait, Ed Schultz and Air America are still around and people are voting blue, WHO would have thought.
