More and more kids are playing video and computer games - especially ultra-violent ones that are top sellers. Research shows that children are also spending increasing amounts of time playing them: an average of 13 hours per week for boys and five hours for girls.
The U.S. Supreme Court agreed last week to hear a case on California's attempt to restrict sales of violent video games to minors. Both the California lawmakers who approved the law in 2005 and the U.S. 9th Circuit Court of Appeals judges who overturned the law in 2009 claimed that scientific research was on their side.
