"This article outlines the early history of the Australian community radio sector. It focuses on three of the country’s oldest stations – Radio Adelaide, 4ZZZ and 3CR – to document the establishment and growth of the sector over the past fifty years. Two theoretical lenses are identified from the literature on Australian community broadcasting, loosely categorized as citizens’ media and empowerment media, and these are evident in the narratives of the case study stations. A third framework – social movement theory – is proposed for further understanding the value of community broadcasting and its contributions to the wider media landscape." (Abstract)
