I watch very little, I usually watch 30 min's a day to get the news... then I check the program, if there is a movie or a documentary on, it has to fill two conditions for me to watch it:
1. it's interesting
2. i haven't seen it yet (so many reruns -> time waster!)
I usually watch one movie and one documentary a week maybe. The fact that I only have six TV channels helps, too. I wouldn't even know when to watch cable or sat TV - I don't even have the time to watch the little bit I do watch! Sometimes I tape it and watch it at another time or in pieces... and you can ff over the commericials, too!
If the two conditions don't apply, there's a big red button on the remote... and off to bed with a good book!
