I am of mixed minds about TV. I love watching some TV and it is a great stress reliever for me. DH and I also have favorite shows (Dr Who and Lost and battlestar Galactica) which we discuss for HOURS after the show. We have netflix and love watching movies on DVD.
The kids have honestly learned stuff from the TV they do watch - the educational stuff like Barney, sesame street, noddy. And often having the TV on for 30 minutes to entertain them is better than me losing it because I need 30 minutes to myself, finish dinner, do the laundry, etc.
At the same time, when I get depressed, it is very very easy to turn the TV on and have it on all day, which saps my energy to do anything. I worry about the things the kids aren't doing if they are watching TV. I worry a lot about the commercialism/materialism with TV and the fact that young kids can't tell the difference between reality and fantasy for a long time. I really hated it when our previous au pair had MTV on for hours - the videos creeped me out.
So our compromise is that we be mindful and deliberate in our TV watching. I like the analogy to alcohol. I drink beer or wine on occasion because I like the taste and periodically, it helps unwind after a stressful day. But I am mindful of how much I consume - if I felt that anyone in our house was using alcohol inappropriately, I'd try to intervene.
So for TV, we try to be mindful. We ONLY watch shows we have TiVo'd. Our TiVo list is pretty short - doodlebops, sesame street, etc. - for the kids, and our favorites for us (Lost, CSI, Dr Who, etc). The kids rarely watch our TV (most of the time it is wildly inappropriate for them).
We have the extended hard drive so we have a lot of shows. Both boys can watch the same show over and over and over, so we never really "run out". And after three shows MAX or one hour (noddy is only 10 minutes, Barney 30 minutes) the TV goes off (dh is pretty keen on keeping the TV off since we have a projector TV and the bulb costs $400 to replace).
We also have a couple baby Einstein videos, but those are generally only used "in emergencies" - like on travel or when I am not home and dh is desperate to calm the kids down.
No TV in their room, ever. DH and I have a TV in our room, but we turn it on maybe once every 6 months.
