A marked increase in gun violence in PG-13-rated movies may necessitate a new PG-15 rating for the industry, according to a new study from the Annenberg Public Policy Center.

The big picture: The study found that the amount of gun violence in PG-13 films, which often sanitize both the bloodiness and consequence of such violence, had more than doubled since the rating's inception in 1985 — and even jumped above R-rated films in recent years.
