We have young DC and we let them watch TV but try to do other things as well. If they're not watching something then the TV is off. I love TV but only watch it in an evening when they're in bed.
As a child I remember my mum watching the soaps (not sure how young I was) and kids' tv wasn't on constantly like it is now. In theory I should be able to watch tv sometimes provided it's family friendly but then I don't want the tv on constantly as it was in my parents' and still is:
