Yes, I do not. And have not for years. My husband watched while he was still alive, but it was not an activity we shared. In fact, it was one I discouraged. With handicapped children, I could not deal with the constant noise. If I vegetated in front of the box, I would never accomplish my homeschool and writing goals. The first year I turned it off, I wrote two books from scratch in just over three months.
I do not have a television for my RV (by choice, I took it out). When we vacation, no telly there either. My children will stand mesmerized before it when they are at friends' houses. That concretes my belief it is not entirely beneficial to them.
I do allow them to watch certain video for educational purposes, but they would prefer the interactive games the BluRays offer over the actual films.
