I like watching ( I say watching but it is more like back ground noise while I am doing something else..kinda multi tasking...) the History channel, Food Network,
TLC, A&E, even learn something once in a while, gave up on CSPAN years ago

When I want to really want to watch something on TV I usually go to AMC, TCM, FX, TVLND for the older movies and TV shows that I dont have to think about too much just watch for the entertainment value.
