a label that is put on films, videos and DVDs, stating who can watch them legally. In Britain, the British Board of Film Classification places films, videos and DVDs in one of five groups, U (Universal) for films which can be seen by anybody, PG (Parental Guidance) for films which may disturb young children, 12A for films where a child under 12 must be with an adult, 15 where no one under 15 may see the film or buy the video, and 18 which only adults may see. The label R18 means that the film can only be shown in specially licensed cinemas, or the video or DVD bought in licensed sex shops. The label 12 is only for videos and DVDs, to show that they are considered suitable for children aged 12 and above. In the US, a film is given one of five labels by the Classification and Rating Administration of the Motion Picture Association of America. These are: G for general audiences, PG for 'parental guidance' (meaning that parents decide whether to let their children see the film), PG-13 for parental guidance for children under 13, R for 'restricted' (which means that children under 17 can only see the film with a parent or guardian (= an adult legally responsible for a child), and NC-17 ('no one 17 and under’) for films which may only be seen by adults.
