The analysis found that the pattern of television violence has remained very consistent over time, reflecting TV's stable and robust institutional position in American society. More than 70 percent of prime-time television programs use violence; this statistic has remained constant over the 22 years since this project was initiated. The rate of violent acts in prime time remained between 5 and 6 incidents per hour. About half of all prime-time television characters commit violent acts, including 10 percent who commit murder. Children's weekend daytime programming remains very violent.
