The Motion Picture Production Code was the set of industry moral censorship guidelines that governed the production of most United States motion pictures released by major studios from 1930 to 1968. It is also popularly known as the Hays Code, after Hollywood's chief censor of the time, Will H. Hays.
The Motion Pictures Producers and Distributors Association (MPPDA), which later became the Motion Picture Association of America (MPAA), adopted the code in 1930, began enforcing it in 1934, and abandoned it in 1968, in favor of the subsequent MPAA film rating system. 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. The office enforcing it was popularly called the Hays Office in reference to Hays, and also later the Breen Office, named after its first administrator, Joseph Breen, who took over from Hays in 1934.
By the late 1960s, enforcement had become impossible and the Production Code was abandoned entirely. The MPAA began working on a rating system, under which film restrictions would lessen. The MPAA film rating system went into effect on November 1, 1968, with four ratings: G, M, R, and X and Geoffrey Shurlock stepped down from his post. In 1969, the Swedish film I Am Curious (Yellow), directed by Vilgot Sjöman, was initially banned in the U.S. for its frank depiction of sexuality; however, this was overturned by the Supreme Court.
The M rating was changed to GP in 1970 and to the current PG in 1972. In 1984, in response to public complaints regarding the severity of horror elements in PG-rated titles such as Gremlins and Indiana Jones and the Temple of Doom, the PG-13 rating was created as a middle tier between PG and R. In 1990, the X rating was replaced by NC-17, partly because the X rating was not trademarked by the MPAA, whereas pornographic bookstores and theaters were using their own X and XXX symbols to market products.
