The second in a series that examines the role of radio broadcasting in the process of socioeconomic and cultural change in three countries with different types of broadcasting organization--Austria, Czechoslovakia, and Venezuela--this volume focuses on Czechoslovakia. It deals with the cultural implications of broadcasting structures and their ownership and financing, with special attention to both commercial and noncommercial advertising, and includes a short description of the historic and legal background of Czechoslovakia's national broadcasting system. Specific chapters cover the position and function of radio broadcasting; history of Czechoslovak Radio; organizational structure (interaction between radio and national organizations and relations with authors, performing artists, and record producers); the program activities (networks, program structure, outstanding programs, external services including Radio Prague's Foreign Language Broadcasts); economic structure; technical broadcasting facilities; and manpower resources. Also discussed are the organization of international events and competitions, program exchanges, and joint preparation of programs; personal contacts and employee exhanges; and participation in international competitions and festivals. A cross section of research activities is provided and three annexes present information on networks and broadcasting, permanent orchestras and ensembles of Czechoslovak radio, and the results of a 1979 audience survey.
