Content rating systems are tools used to classify media, such as movies, video games, and television shows, based on their suitability for different audiences. These systems provide guidance on the age appropriateness of content, helping consumers make informed choices. Common rating organizations include the MPAA for films and the ESRB for video games, each using specific criteria to assign ratings. Ratings typically range from suitable for all ages to restricted content, indicating the presence of violence, strong language, or adult themes. By using these ratings, parents and guardians can better protect children from inappropriate material while allowing them to enjoy age-appropriate entertainment.
