I watch almost none at all. I would say I average maybe 4 hours a month. Mostly because I get sucked into Animal Planet. We have one very small TV that is forever plus a year old. The kids do watch. Too much in MHO. My husband and I don't.
One reason is that I can not stand "Reality TV"
I don't watch news because I think they have gone way over the line on what is acceptiable to air, I just don't want my kids seeing that stuff.
I do watch a few TV shows on disc- West Wing (I am on season 4), right now that is all, but my son says I should watch the 1st season of 24 so I might try that. I watch them on my laptop though, not a TV.
I am a sucker for a rerun of MASH so if I happen onto one I will watch that.
I might watch an episode of Monk every now and again.
I sometimes watch reruns of Little House with my daughter.
Oh and I do watch some of the Comedy Central stuff people upload to that one site which I can not think of the name right now...
I also watch Ask a Ninja online.
I spend all my free time online (and a good bit of time that I should be doing other things)
