Parents set rules on what their kids can watch on TV, but did you ever wonder who decides if a movie will be rated ‘G,’ ‘PG,’ ‘PG-13,’ or ‘R’?

The Motion Picture Association of America (MPAA) uses bad language and violence to decide how old you must be to see a movie without an adult (anyone for ‘G,’ ages 13-16 for PG-13, and age 17 and up for R).

On May 10 the MPAA announced that it will consider cigarette smoking in movies when deciding ratings. For instance, if teenage characters smoke in a movie, the MPAA might give it a stricter rating.

Ratings are designed to make sure kids have good role models on the big screen. MPAA Chairman Dan Glickman said, “Clearly, smoking is increasingly an unacceptable behavior in our society. … No parent wants their child to take up the habit.”
