Wow. Watching TV is already well down on my list of recreational activities, done only occasionally maybe one night per week (two nights, if it's an especially boring week). If they want to start charging for OTA then they'll probably lose a lot of viewers. I like playing the piano and reading better anyway.
TV is funny - the more you watch, the more you think you have to watch. The less you watch, the less you want to watch - even when you have nothing else to do. I've been moving towards less and less for a few years now. I was thinking of canceling Dish and going with only the DTVPalDVR and OTA. But if they're now planning on charging for THAT too, well, my piano expertise will improve with the additional practice, and I'll get more books read.
