NAB Seal of Good Practice logo, commonly used from 1958
to 1964.

The code prohibited the use of profanity, 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.
