I think the biggest format hole is still Variety/Adult Hits, with soft AC as a distant second.
Having said that, why hasn't Cox done more with WSB-FM-HD2, especially compared with what they have done with TOSOTR online and with translators?
There are a lot of players monkeying around with newer rock (both alt and active), between 99X, Radio 105.7, TOSOTR, and Rock 100.5's dabblings. I don't see any fresh ground to till there.
Could an intown Cumulus translator bite into the urban apple that is currently owned by Radio One, Cox, and CBS?
Does anyone know how Chuck FM does in their nominal market (they're not considered to be an Atlanta station)?
Could Cumulus put variety hits on 106.7, shutter the news operation, and move the talk to 98.9 and make a go of that with some canned news? They could turn off the stereo and get a little more range.
