The third 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 Venezuela. An overview of radio broadcasting in Venezuela describes various aspects and provides a structural analysis of the system components, with particular reference to the organization of ownership and the use of assigned radio frequencies. A diachronic comparison of the evolution of radio broadcasting in Venezuela (1947/1980) is also provided. An economic analysis of Radio Rumbos/Rumbos Compania Anonima, one of the most important stations, considers the investments, expenditures, and income of the station, which is representative of the present situation of organic, functional, and financial concentration characterizing radio broadcasting in Venezuela. Based on a review of one week's broadcasts from Radio Rumbos, the concluding chapter discusses the contents and concomitant program organization of the radio broadcasting system, emphasizing the relationship between economic factors and station programming.
