Age rating is a system used to classify content, such as movies, video games, and television shows, based on its suitability for different age groups. These ratings help consumers, especially parents, make informed decisions about what is appropriate for children and teenagers. Common age ratings include G (General), PG (Parental Guidance), and R (Restricted). Different countries have their own age rating systems, such as the MPAA in the United States and the BBFC in the United Kingdom. Each system evaluates content based on factors like violence, language, and sexual content, providing a clear guideline for audiences regarding the material's appropriateness.
