"This dissertation analyzes the participatory community radios of post-war El Salvador through ethnographic research and analyses of their operations and programming. It explores the concrete local meanings of civil society and the ways this medium helped construct a vibrant popular culture. Its core is an analysis of the relationships between the community radios and the activities of emerging civil society organizations as part of a post-war movement reflecting a Gramscian discourse of civil society. Examples show how their collaboratively produced programs sought to increase popular participation especially among the formerly marginalized rural and urban poor, as well as to deepen understanding of human rights, promote practices of citizenship, and redefine “news” to fit their particular audiences. A viable civil society depends on the availability of public spaces. The dissertation investigates the issues underlying the battles to legalize the community radios and expand this virtual public space. Analyses of radio broadcasts of school graduation celebrations demonstrate the radios’ central role in activating the local public sphere, building on critiques of Habermas’ foundational concept (1989). Community radio is not a smaller version of commercial radio, promoting consumption which listeners arguably use to create a feeling of belonging (Garcia Canclini 2001). Instead, these radios are a form of popular culture: transformative expressive practices which reconnect people to their own agency and through which they construct a sense of collective identity (Rowe and Schelling 1991:7)."
