Online Radio Ads

I don’t have a stereo receiver at home. On occasion, I like to listen to a local radio station online via iTunes. My biggest gripe are the ads. Do radio stations really need to play 15 minutes of ads before I hear the actual show? The only reason I stuck around was to find out how long the ads would run. 15 minutes of ads! You got to be kidding me. No one has that kind of patience just to hear a radio show. So now, I have this policy. If I hear ads, I simply switch stations. I know radio stations have to make money, but 15 minutes. Annoying if you ask me.
