Since the rise of television, much radio consists of 'capsule' news and music formats which are heard as background to other activities. However the medium offers a great deal more. This collection of essays shows how in North America, the United Kingdom, Europe, Australia and the South Pacific, radio continues to provide distinctive forms of content for the individual listener, yet also enables ethnic and cultural groups to maintain their sense of identity. Ranging from radio among the primordial communities to digital broadcasting and the internet, these essays suggest that the benefits and gratifications which radio confers remain unique and irreplaceable in this multi-media age.
