Reporter: In 1985 the average pg 13 had less than one shooting per hour, in 2012 nearly three shootings per hour. Sex and swearing will still earn on r rating but gun violence pg 13. A top grossing film of today will have less gun violence than a top pg 13 today. Reporter: The motion picture association declined comment.
