Yes, I don't have a television and I know a lot of other families who don't own one. (A good percentage of them don't have internet at home either.) No one I know seems to be suffering from the lack of television.
I find that I hardly have enough time to get everything done the way it is...When would I find the time to watch TV on top of everything else? I have enough time-wasting hobbies that are still more productive. :)
