From the FTC:
The FTC released their report on September 11, 2000, and their findings seem to confirm what many have suspected for some time.
The Executive Summary of the report reveals, "Scholars and observers generally have agreed that exposure to violence in entertainment media alone does not cause a child to commit a violent act and that it is not the sole, or even necessarily the most important, factor contributing to youth aggression, anti-social attitudes and violence." However, the report goes on to say, "The Commission's literature review reveals that a majority of the investigations into the impact of media violence on children find that there is a high correlation between exposure to media violence and aggressive, and at times violent, behavior. In addition, a number of research efforts report that exposure to media violence is correlated with increased acceptance of violent behavior in others, as well as an exaggerated perception of the amount of violence in society"
This is just another example of putting the cart before the horse. Lets use an example to illustrate this. Man A is a golfer. Man B is a tennis player. Man A enjoys watching golf on television. Man B can't stand it. Of course the more violent children watched more violence on television, and played more violent video games...that's what they were into!
Sexuality however, is more accepted, and thus is more readily seen on regular television programs, and even commercials.
I don't think that anyone here would dispute that television, and the media have influence. Of course they do. But there is a big difference between influence, and being cited as being responsible for the sex and violence in society today. Sex and violence are in the media because they sell. If there wasn't a market for it...you wouldn't see it. Therefore, it is the "effect", not the "cause".
