We have never let our children watch TV, even football games and the so-called "Discover" channel, unsupervised for the simple reason that they will be subject to gratuitous images of violence for movies and shows. Personally if I had a choice I'd rather my kids see beautiful images of the human body than dead bodies and guns. Ultimately parent's need to stop trusting profit based companies from determining what their family is watching and take responsibility to either turn off the TV or watch with your family and skip commercials. If you don't have the time to do that then your kids shouldn't be watching TV. Remember, you are not only what you eat but also what you see, listen to and do.
