Pulling Down the Walls of the World, 1920–1930
This chapter traces the origins of international broadcasting in the 1920s, examines cooperation among broadcasters working to control and regulate transnational transmissions, and analyses utopian ideas about the impact of radio on the international order. It draws out the early history of cross-border broadcasting and listening and demonstrates that in the first years of radio, all listeners were distant listeners. It explores the technologies of transmission and reception used in international broadcasting during the 1920s. It discusses why many contemporaries thought that broadcasting could encourage international understanding and peace in the wake of the carnage of the First World War. It argues that wireless internationalism found its most obvious expression in this period with the foundation of the International Broadcasting Union (IBU). The IBU encouraged members to exchange material with one another and relay each other’s programmes. Finally, the chapter explores the early history of short-wave broadcasting and relay work, and examines debates about the establishment of a BBC empire service.
