Latin American mass media are going beyond the mere production of information to become agents of social projects from a corporate and socially responsible framework in alliance with external players, particularly civil society organizations (cso). This paper puts forward the results of research work which collects, for the first time, the experiences of some of these alliances between media and cso in Latin America and Colombia for the benefit of Democracy and Human Rights. Via interviews with some of the main players, the study identifies both challenges and lessons for future alliances in an attempt to strengthen the contribution of mass media to the development of democracy and human rights in Colombia.
