(WJLA) - Depictions of violence in movies has increased so much that its skewing traditional movie ratings, a new study indicates.
According to the report, which was published Monday in the journal Pediatrics, gun violence in movies rated PG-13 has tripled since the 1980s and has gone past the amount of violence in movies rated R.
The Washington Post reports that the study's authors studied the 30 highest grossing films from each year between 1950 and 2012, during which they discovered the enormous uptick in the depiction of gun crime.
Overall, the study reveals that violence in movies overall has doubled since the mid-20th century.
"We think that the PG-13 rating is no longer very helpful," Dan Romer, a co-author of the study, told the Post. "If they're going to allow content like that in PG-13 movies, it sort of goes against the grain of how they define the difference."
The PG-13 rating was rolled out in 1984, the Motion Picture Association of America says, with the intention of allowing parents to make further inferences about whether or not to let their young children see movies with the rating.
