This paper traces the development of federal regulations of the broadcast industry aimed at controlling the industry's monopoly abuses within the United States, and describes the development of the industry's major network domination of the media markets and audiences throughout the world. Suggested reasons for this transnational domination include absence of effective governmental regulations, network expensive production quality, and high production costs unattainable by developing countries. The author cautions that the major network domination of the United States and international market leads to cultural pollution since the networks' major emphasis is upon building large audiences rather than program quality.
