The 1970s were highlighted by government intervention into the media system in Korea. In 1972, President Park Chung-hee government imposed censorship upon media through the Martial Law Decree. The government revised the Broadcasting Law under the pretext of improving the quality of television programming. After the revision of the law, the government expanded its control of media content by requiring all television and radio stations to review programming before and after transmission. Although the government argued that its action was taken as a result of growing public criticism of broadcasting media practices, many accused the government of wanting to establish a monopoly over television broadcasting.
