A self-regulatory code of ethics created in 1930 by the motion picture industry, under Will H. Hays, and put into strict effect in 1934, with Joseph Breen (of the Breen Office) as director of the Code Administration. The code set forth general standards concerning what could and could not be shown in American movies. Among the general principles of the code was the requirement that "no picture shall be produced which will lower the standards of those who see it. "The specific regulations forbade justified revenge; explicit presentation of crime methods; explicit presentation or acceptance of "low forms of sex relationships," including adultery and prostitution; "excessive and lustful kissing, lustful embracing, suggestive postures and gestures"; "miscegenation" (sex relationships between the white and black races); and "pointed profanity."
