Hours spent watching TV correlates to bullying and violent behavior in children
Each hour of TV watched daily by children under age 4 increased the risk that they would engage in bullying by 9 percent by the time they started school [1,2].
The American Association of Pediatrics estimates that 10 to 20 percent of real-life violence can be attributed to exposure to media violence [1,3].
