It's not working there either. The examples you give are being killed by better run stations in those small towns. The only advantage is the losses aren't as fatal. But as I've said in other threads, at some point these stations are going to have to shut down their web streams, because they're eating up any money they make. It's all expense and no revenue.
So if it's not working, why are they still on the air, broadcasting classic hits? It's certainly no KRTH, but for them, it has to be working, right?
