A history of alternative media, beginning in the 1960s: from revolutionary press experiences to the mediactivism of the alter-globalization movement, the free radio movement, or the creation of press agencies in southern countries.

Over the 20th century, mediactivism has set itself up in opposition to dominant media conglomerates. From the outset, mediactivism has taken two parallel paths: one struggling against the cultural hegemony of traditional media, and the other producing another kind of information based in local, activist, and community circles. This history of alternative media since the 1960s sets out to demonstrate its variety: revolutionary press experiences, community media, internet activism, the free radio movement, and news agencies in countries of the southern hemisphere.
