The BBFC classifies films in the UK based on their age ratings. Films featuring violence, nudity or other mature content receive higher age ratings like 18, while family friendly films are rated U. The BBFC was established in 1912 and uses universal symbols to easily convey a film's rating. OFCOM regulates television broadcasting in the UK and ensures programs adhere to its codes on harmful or offensive content, like restricting violence before the watershed. The watershed at 9pm aims to separate more adult content from programming for children.
