Rating and restrictions.

Movie ratings provide parents with advance information about the content of movies to help them determine what’s appropriate for their children.  This helps the parents as they  know best children’s individual sensitivities. Ratings are assigned by a board of parents who consider factors such as violence, sex, language and drug use and then assign a rating they believe the majority of  parents would give a movie.

However it is not only film that get rate restriction, for example adverts are only shown on certain channels, and posters can only be shown in certain places for example an 18 rated wont be displayed in a school.
