Tube of Plenty is an abridgement of Erik Barnouw's classic 3-volume History of Broadcasting in the United States. The paperback edition was first published in 1976 and a second edition in 1982. Much has happened in television in the 1980s; the decline of the three major networks, the expansion of cable and satellite television, film channels like Home Box Office, the success of ESPN (sports), and MTV (pop music), and the increased way in which the White House in Washington has managed and controlled national news and its contents. Barnouw has added an extensive chapter dealing with the changes of the 1980s and looking ahead to the 1990s.
