After a federal judge ruled in 1982 that some stipulations of the National Association of Broadcasters' (NAB) Television Code were violating antitrust laws, the NAB responded by suspending all code operations. Effects of the suspension on network advertising included (1) the disappearance of preclearance for commercials about cholesterol-related products and for advertising aimed at children; (2) the acceptance of some advertising, especially by local stations, formerly prohibited by the code; (3) a greater burden placed on the advertising industry's own regulatory agencies; (4) a lack of interest among top officials of the NAB in reformulating the code; and (5) greater efforts by the Children's Advertising Review Unit and by major networks to uphold the standards of the old NAB code. Thus, while the disappearance of the television code brought some changes in advertising practices, a number of agencies have accepted much of the burden of reviewing and regulating commercial advertising.
