Book excerpt: This book addresses new conceptual bases for thinking critically about communication as a necessary way in which to confront power, property and the market as part of the daily resistance of Latin American subaltern cultures. The chapters research an urgent field of situated knowledge and spark a much-needed dialogue. The editors view emancipatory communication experiences as disruptive acts of resistance, prompted mainly by social movements. These experiences have opened up political modes of communication by establishing a decolonising axis in the field of communication and reconstructing the history and memory of Latin America. This book is a valuable reference for researchers, academics and students interested in the role of communication and culture in processes of social transformation.
