This document discusses alternative communication theory from a post-colonial perspective, focusing on contributions from Latin America and Mediterranean Europe that have been overlooked or underrated. It analyzes the works of Gramsci and Freire, noting that their theoretical frameworks emerged from specific historical contexts and experiences that are often left out of analyses. It also discusses the state of alternative communication research and debates in Latin America, Spain, and Italy since the 1970s-1980s, and proposes strengthening international research associations to improve global exchange of approaches from different origins.
