Take an area like Myrtle Beach SC with hundreds of golf courses. Would have to make deals with hotels and rental agents to have the station on in each room. Sell advertising to golf courses, restaurants, bars, strip clubs, golf shops, etc.
I could see a format clock like an all news station with a 20 or 30 minute cycle - weather, course conditions, golf tips, restaurant reviews. Some real news and sports (golfers do care about world issues).
In addition to spot advertising, you could sell features on new courses, area attractions, etc.
Problem presented is the seasonal nature of the sport in most locales. Even a golf meca has an off season. Advertiising pricing would have to be structured to encourage year-round advertising.
It could work - in limited areas.
