20 minutes of commercials per hour 24/7? Sounds like a bit much - four 5 minute breaks plus any news or local -
Ever been to Chipley? WBGC won't be playing any Arbitron games, so TSL & AQH don't matter. If this 1-kw AM in a town of 3600 people in a county of 22,000 has any reason for existing, at all, it isn't to battle the dozen FM sticks booming in from Dothan & Panama City over who can play the most music. It will be solely about providing hyper-local information and promoting local teams, local causes & local organizations. Whatever music WBGC will play--if it chooses to play any at all--will be incidental, since nobody is going to listen to the station for music anyway.
Twenty announcements each hour about local businesses isn't too much if the station exists to provide information about the local community. Besides, that presumes they actually sell out. They (we all) should be so lucky!
