Good for you. I still have one but it is not hooked to an antenna. We just use it for videos or DVDs and that is usually just 1-2 nights a week, and even then there goes by many a week when I don't watch the fool thing at all. I've managed to fill the time with other stuff.
I don't know who is still on the air and who isn't. The last program I used to watch regularly was Cheers and I don't even know if it is still on. Probably not by now.
