*Winner of the AEJMC-Knudson Latin America Prize 2017* Social movements throughout contemporary Latin America are successfully influencing and shaping media policy. In this highly original, detailed, and in-depth study, Silvio Waisbord and Maria Soledad Segura scrutinize the goals, tactics, and impact of civic media movements across the region, demonstrating the full extent of media activism on domestic policy and politics. Media Movements goes beyond simple conceptions of 'the national' versus 'the global' to reveal the complicated process of media policy-making, and to evaluate the significance of local political elites and citizens, global actors, and legal frameworks. With success rates varying across the region, the authors offer an assessment of the impact of citizens' mobilization on policy-making, as well as the effects of legislation on ownership, funding, community media, non-profit media, and public media.
