By the way, I will now look at this theme for adults. Grown people have an ability to choose or judge about each TV program, or they should have, so TV is better for adults than children. Adults can know a lot of things around the world from TV, and think about them by themselves as well as enjoy watching it. But actually, there are many people who don't watch TV usefully. I think many people watch TV only to enjoy it or just for the sake of watching it, so if those who watch TV meaningfully are increasing, TV is more effective for our life.
Indeed, the problem is not about TV but the people using it!
