WASHINGTON (AP) -- The Kaiser Family Foundation says some two-thirds of the parents it surveyed say they're very concerned about sex and violence that children are exposed to in the media.

The survey also indicates there would be broad support for new federal limits on such material on television.

The report also finds that two in three parents say they already track their children's television viewing and use of the Internet and video games.

Only one in five parents conceded they should do a better job of watching what their kids watch.

The study is being released today in Washington.
