lol, i am one of those people! i don't thinm it;'s the same as tv though.
personally i was sick of dp coming in each night, sitting on the sofa, and not getting up until he went to bed
and i was tired of having cbeebies on a loop because it was "easy"
so we stopped it. we save money (another reason for doing it) by not having a tv licence or the tv service from virgin.
we do have DVDs for the children, but no advertising, and it isn't so easy to just leave it on all day. when it ends it ends.
the main reason we kept the tv was so that we could play on the wii as well though lol
tbh it has made a difference, I think I had got into a rut of using the television as background noise, or to entertain the children. so it has meant that I spend more time doing stuff with them. and dp and I talk more, and get housework done (sometimes) which is good.
depends what kind of person you are though. If you can regulate how much you watch then great! i have no real problem with television, or kids watching it. just, in our case it was getting to be a problem and we are unable to control ourselves clearly! lol
