The BBFC (British Board of Film Classification) classifies films, trailers, videos, online content, mobile content, educational videos, music videos, and video games shown in the UK. They use a rating system of U, PG, 12A, 15, 18, R18, and X18 to indicate the appropriate audience for the content. The BBFC examiners consider factors like context, theme, discrimination, drugs, imitable behavior, language, nudity, sex, threat, and violence when determining a rating. The seven ratings are classified differently based on what types of content are appropriate for different age groups.
