Talking to a friend this evening, I confessed to not being entirely certain when the last time was that my TV was switched on. I have two major reasons for this:

1. Reality programming. (For example, I’d prefer to go on my own camping trips instead of watching Survivor.)
2. Ads that run during the program. Not during the breaks in the program, but the crap they put on the screen after the commercial breaks that distracts you from the show you’re trying to watch.

(I would have also listed “General Lack of Quality Programming”, but that would have been redundant with the first item.)
Thursday’s User Friendly strip points out another good reason to leave the TV turned off.
