I can honestly say that my children don't watch much TV with the current exception of ds3 who has recently become obsessed with CBeebies. His obsession does worry me, but I know in my heart of hearts that if I really didn't want him watching it, he wouldn't watch it (eg at the weekends, I tell him CBeebies isn't on and he accepts that and doesn't turn the TV on). He will outgrown CBeebies before long.
Dh and I watch a reasonable amount of TV in the evening. We would always trun the TV on each evening to see hwta is on, but we have been known to switch it off again if there is nothing we like. We don't watch it mindlessly.
I would not like to be without the TV. I positively enjoy some programmes and frequently enjoy just vegging out after a hard day in front of something reasonable. Also, the thought of not being able to watch TV when ill is frightening.
