Excellent show. I'm getting that TV broadly increases language skills by putting words into context with experiences. Especially experiences OTHERS are telling us about because we're ultimately safe. Even fictional OTHERS. Language, or expression, is a beneficiary of story-related education. The locality of stories tends to make us more aware of other's societies so increases tolerances and fears. In that way it may have led to a more liberal society but one which is also more afraid of threats. That is how imbalances come about.
TV can be bad for you but it can be good for you. It's like food. If you consume nothing but junk then it will have a harmful effect on you. Consuming too much can also be bad for you. And there is a LOT of junk on TV.
