Way Way Way too early to call 1200 a failure.
Not that I'll ever listen, nor will anyone I know, but I'm sure there's a market for it and it will take them months if not years to find it.
I mean crap I wouldn't even know "Rush Radio" existed if I didn't read this board. Give people more than a month to find it before you call it a failure.
And like someone mentioned, it's costing them very little to run, so even if they are just clearing more of their national spots it's probably a win for them.
As for WEEI yes the spike is normal, April means baseball, a reason for 100s of thousands of Sox fans to keep the radio on all night 6-7 days a week. Not to mention Celtics playoffs, and all the "talk" that goes along with the Sox starting, C's/B's playoffs, Pats draft, etc.
As for WBMX, it's the nature of any Mix/Mike/Frank/etc type station I think. People check it, it may even be their P1, but the average listener is going to check it, see if they are playing a song they like, and then either stay or keep flipping depending on the song. Whereas WBUR who has 1/2 the cume but almost the same rating, are listeners that may listen for 6-hours a day not flipping around at all.
I know it's still too early to tell, but I'm a bit surprised that the WGBH changes aren't helping them more. Even 4-5 months after the changes have sunk in they are still losing ground to WBUR. Too little too late?
