Control of the content and presentation of films. Film censorship dates back almost as far as the cinema. In Britain, censorship was established in 1912, in the USA 1922. In some countries, self-regulation of the industry has not been regarded as sufficient; in the Soviet Union, for example, state censorship has forbidden the treatment of certain issues. Censorship in Britain was the responsibility of the British Board of Film Censors (now the British Board of Film Classification) which gives each film a rating. In Britain, children were not prevented from seeing certain films until 1933, when the `H' (for `horrific') certificate was introduced. In the USA, censorship was not established until 1922 with the founding of the Motion Picture Producers and Distributors of America (see Hays Office).
