There are no TV shows that I watch really. We have a Netflix subscription and I get things like West Wing, Sopranos and documentaries through there as well as movies.
Other than those DVDs, I would say I spend less than 2 hours a week watching TV. I think I am the only person in the world who has never watched a full episode of Seinfeld, Survivior (or any other reality show) or any CSI or Law and Order type stuff.
I will sit and watch the Simpsons if I see it on and some History/National Geo/Discovery type shows.
