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