Two-thirds of American dramatic TV programs depict violence at eight assaults per hour.

Evidence

Various survey studies have shown that the American televised world is a rich source of violence. Gerbner (1972b), who has conducted the most comprehensive yearly analyses of televised violence, reports a stable violence rate of eight assaults per hour, with approximately 66% of dramatic programs containing violent activity involving either commiters or victims of violence. — Albert Bandura, Moral Disengagement, 799
