The Supreme Court issued a 7-2 ruling today rejecting the California law banning the sale or rental of violent video games to children.
California wanted to prohibit selling or renting violent video games to anyone under 18, but federal judges have ruled that the law violates First Amendment free speech rights.
Justices seemed closely split in November during oral arguments, with some arguing that parents need help protecting children from violent games like "Grand Theft Auto IV." Other justices seemed reluctant to carve out an exception to the First Amendment to cover violence in video games.
Over 46 million American households have at least one video-game system, with the video game industry bringing in at least $18 billion in 2010.
