The British Board of Film Classification (BBFC) is a non-governmental organization that is responsible for classifying films, videos, and video games in the UK. It assigns ratings to help protect children and other vulnerable groups from unsuitable material. Films that are considered obscene or would deprave/corrupt viewers can be refused a certificate or banned. In the past, controversial "video nasties" led to increased regulation and bans. While classifications aim to curb harmful influences, some question if they are still effective in the digital age.
