Violence on TV shows empowerment and that people can do things bad and get away with it. It is giving people the wrong messages. Really there has been no solution and realistically there may never be one. Sometimes violence is also necessary to portray what happened in real life. There are other negative aspects of TV as well.
Sex is another big issue.
The casualness of sex on TV is shocking. It is amazing that they don't show how many STD's these people are getting also. Not saying that all TV is bad, there are some good shows, and it seems more back in the day then today with moral values and a point. People seemed to learn from these things. The episode where DJ decided she wanted to be anorexic was a good episode for kids watch because at the end of the show, with the corny background music, they explained why it was wrong and why you shouldn't need to want to change your body image.
