I believe the thinking behind this move is that the first station to flip to Christmas gets all the listeners, and any station that follows after that doesn't do nearly as well.
At least, that seems to be the thoughts on some radio piece I read the other day.
It might work when it's one full power AC versus another, but for an LPTV to get the jump? I doubt anyone will notice, except the angry Pig fans (if there even are any).
