"Written from a social and cultural perspective, Dirty Discourse concentrates on the means of greatest distribution - radio, with its phenomenal growth of "shock jocks" and rap music lyrics, and provides coverage of television and the Internet. The book shows how and why broadcasting has evolved from the ribald antics of the Roaring 20s to today's streaming cybersex, contrasting the standards and actions of the FCC v. the First Amendment amidst the over-the-air and in-the-court battles of over-the-top radio. It examines political pressures and legal considerations, including Supreme Court decisions, and efforts to protect children from media smut."--BOOK JACKET.
