The Motion Picture Production Code was a set of industry guidelines for the self-censorship of content that was applied to most motion pictures released by major studios in the United States from 1934 to 1968. It is also popularly known as the Hays Code, after Will H. Hays, president of the Motion Picture Producers and Distributors of America (MPPDA) from 1922 to 1945. Under Hays’s leadership, the MPPDA, later the Motion Picture Association of America (MPAA) and the Motion Picture Association (MPA), adopted the Production Code in 1930 and began rigidly enforcing it in 1934. The Production Code spelled out acceptable and unacceptable content for motion pictures produced for a public audience in the United States. (Wikipedia)
