Parents urged to limit 'virtual violence' for kids

The American Academy of Pediatrics is urging parents, doctors and the media to help limit the amount of 'virtual violence' kids are watching on TV, the internet and video games.

Some studies link it to aggressive behavior.

But even without the scientific evidence, most experts agree it makes sense to limit kids' exposure to violence whether it's real, such as on the news, or in video games.

The academy says parents should shield kids under six from all violent images.

For older kids, it also says parents should play the video games their kids are playing so they know the content.

Also ban first-person shooter games.

They also urge the entertainment industry not to glamorize violence.
