I've got a better suggestion for you, just don't watch TV at all. I can't even watch a football game anymore as it seems to be more of a commercial-a-thon with a little football in there to break it up.
I've been trying to break TV's grip on me for quite a while. It can definitely rise to the level of an addiction. In the 90's I went a couple years without a TV in the house, but in all honesty, I feel like it did make me a little out of touch with my "culture" (such as my culture is). My wife watches a lot of TV too; I'm working on her to read more, watch TV less. Also I need to get us a second computer so we both can be online at the same time. Want to get WiFi so we can kind of be together in the living room as a family and work on the computers together, have some interaction.
All that said -- it's still nice every once in a while when I'm exhausted and have worked hard to veg out for a few hours in front of the boob toob. It's also nice when something important has happened or is happening (9/11, a Presidential debate) to have a TV.
