Book excerpt: "Radio Cultures examines the manifold ways in which radio has influenced the nation's social and cultural environment since its inception nearly a century ago. Written by leading scholars in the field, chapters address a wide range of topics, including how this powerful medium has impacted and affected non-mainstream segments of the population throughout its history and how these repressed and neglected groups have employed radio to counter and overcome discrimination and bias. The use of the audio medium for political, economic, and religious purposes is comprehensively probed and analyzed in this insightful and innovative volume."--Back cover.
