Over half of all children have a television set in their bedrooms. This gives a greater opportunity for children to view programs without parental supervision. Studies reveal that children watch approximately 28 hours of television a week, more time than they spend in school. The typical American child will view more than 200,000 acts of violence, including more than 16,000 murders before age 18. Television programs display 812 violent acts per hour; children's programming, particularly cartoons, displays up to 20 violent acts hourly. How does televised violence result in aggressive behavior? Some researchers have demonstrated that very young children will imitate aggressive acts on TV in their play with peers. Before age 4, children are unable to distinguish between fact and fantasy and may view violence as an ordinary occurrence.

In general, violence on television and in movies often conveys a model of conflict resolution.

There are other, new forms of violence to which children and adolescents are exposed. In one recent study, it was demonstrated that 15% of music videos contain interpersonal violence. Still another new source of violent exposure is access to the Internet and video games. There is little data on the incidence of violence on the Internet; however, there is concern about sites that may advocate violence, provide information on the creation of explosive devices, or reveal how to acquire firearms. There is also little research on the impact of violent video games. We do know, however, that they are extensive and have a role-modeling capacity.
