On August 10, 1984, the action thriller Red Dawn, starring
Patrick Swayze, opened in theaters as the first movie to
be released with a PG-13 rating.

The Motion Picture Association of America (MPAA), which
oversees the movie rating system, had announced the new
PG-13 category in July of that same year.

Founded in 1922 as a trade group for the American film
industry, the MPAA introduced its first-ever movie rating
system in November 1968.
