Using information gleaned from books and other published materials, this report traces the history of international broadcasting from its earliest days (1915) to the present. The report also takes a look at the impact of these broadcasts, and how this impact can be measured. It then considers the reason why there are so many international broadcasters, most of whom persist in spite of the difficulties and rising costs. After discussing jamming--attempts to stop people from listening to international broadcasts from other countries--the report looks at some of the problems that broadcasters face today and considers the future of the medium. The report is divided into the following sections: (1) introduction, (2) the early years, (3) the 1930s explosion, (4) the war years, (5) postwar and the 1950s, (6) the 1960s, (7) the 1970s and 1980s (commercial international broadcasting and domestic broadcasters as international broadcasters), (8) the impact of international broadcasting, (9) the problems of communication and international broadcasting, and (10) the future of international broadcasting.
