Book excerpt: In the twenty-first century, community radio is fulfilling an increasingly important role in the world's mediascape. This book documents the ways in which community radio broadcasters and activists are using the medium in countries around the world to challenge political corruption, aid the transition to political democracy and broadcast voices that are otherwise unheard. The contributors to the volume are academics and practitioners from five continents, many with first-hand experience of community radio. Each chapter demonstrates the pivotal role that small radio stations can play in developing, sustaining and invigorating communities. The book charts campaigns for the legalisation of community radio and relates them to a theoretical context, while providing illustrations and examples from community radio stations around the world.
