When they were under 6, it was mainly DVDs on a Saturday afternoon. Family all watching together for an hour or two once a week. Except for when dd was under 4; didn't have a TV then.
Now they are 8 and 12, but still have to ask permission to switch on the telly/watch a film. And I won't give it every day, particularly not in the summer. They don't watch more than an hour a day spread out over the week.
They didn't have computers/DSs/Wiis when they were under 6. Dd (12) has a DS now, but ds (8) has been told he needs to improve his reading first.
Dd uses my work computer, but really needs her own because of her disability. Ds could do with one too, for same reason, but no money just atm.
I've never noticed TV becoming very desirable because of being rationed, as needmorecoffee says. I think more my dc's have got used to other ways of entertaining themselves.
My dn otoh who has no TV restraints will sit inside for hours watching even on the sunniest summer day, because he is hooked. He gets very whingey when he can't watch for some reason. He expects some visual entertainment even on the shortest car journey.
I don't particularly have a dislike of TV, just not terribly interested myself, so tend not to know what's on.
But I wouldn't like to have my kids always sat in front of it the way my dn's do, wanting to eat their meals in front of it, preferring it to playing outside.
