The code was first issued on December 6, 1951, and amended multiple times, especially in the wake of the
1950s quiz show scandals, Congressional hearings into violence (1952, 1954), and concern over the possible blurring of fact and fiction in early docudrama. The code prohibited the use of profanity, the negative portrayal of family life, irreverence for God and religion, illicit sex, drunkenness and biochemical addiction, presentation of cruelty, detailed techniques of crime, the use of horror for its own sake, and the negative portrayal of law enforcement officials, among others. The code regulated how performers should dress and move to be within the "bounds of decency". Further, news reporting was to be "factual, fair and without bias" and commentary and analysis should be "clearly defined as such". Broadcasters were to make time available for religious broadcasting and were discouraged from charging religious bodies for access. Most importantly, it limited the commercial minutes per hour. In 1973, responding to concerns raised by
Action for Children's Television, the NAB revised the code to limit commercial time in children's programming to twelve minutes per hour. Additionally, the hosts of children's television programs were prohibited from appearing in commercials aimed at children. This became Section XIV "Time Standards for Non-Program Material". ==Enforcement==
