Book excerpt: The Bloomsbury Handbook of Radio presents exciting new research on radio and audio, including broadcasting and podcasting. Since the birth of radio studies as a distinct subject in the 1990s, it has matured into a second wave of inquiry and scholarship. As broadcast radio has partly given way to podcasting and as community initiatives have pioneered more diverse and innovative approaches so scholars have embarked on new areas of inquiry. Divided into seven sections, the Handbook covers: - Communities - Entertainment - Democracy - Emotions - Listening - Studying Radio - Futures The Bloomsbury Handbook of Radio is designed to offer academics, researchers and practitioners an international, comprehensive collection of original essays written by a combination of well-established experts, new scholars and industry practitioners. Each section begins with an introduction by Hugh Chignell and Kathryn McDonald, putting into context each contribution, mapping the discipline and capturing new directions of radio research, while providing an invaluable resource for radio studies.
