There is almost always a violent television show on tv. There is violence in movies, video games, and even cartoons for young children. More shows are now adding violence to cartoons because it attracts children and young adults to watch it. It is also teaching children violent acts that they partake in with other children.
There is also a lot of violence in adult television shows. I can think of 5 violent television shows on the top of my head: CSI, Law and Order SVU, NYPD, Cops, and SWAT Dallas. I only put down 5,but there are sub types of shows like CSI New York, and Law and Order.
Not only do you see violence in these created shows, but all you hear on the news now is local and worldwide violence. You hear about beatings, children getting raped, suicide bombers, etc. It is sad how the saying, "If it bleeds, it leads" is very true to Americans.
