Grupo Octubre is an Argentine multimedia conglomerate created and directed by Víctor Santa María, Secretary General of the building workers union Sindicato Único de Trabajadores de Edificios de Renta y Horizontal (SUTERH) and former president of the Peronist Partido Justicialista in Buenos Aires. Administered by the Fundación Octubre de Trabajadores de Edificios, established in 1991, the group claims a unique ownership structure as the only media conglomerate in the world owned by a labor union rather than individual proprietors. Describing itself as “a creative and plural space that develops, brings together and promotes different cultural, educational, solidarity and communication undertakings,” the organization began with cultural and educational initiatives before expanding into media. Holdings include Página 12 newspaper (acquired 2016), Caras y Caretas magazine (relaunched 2005), El Planeta Urbano magazine, AM 750 radio, FM Malena 89.1, FM Aspen 102.3, OctubreTV streaming platform, and Latinoamérica Prensa portal. Educational institutions include the Instituto Superior de Octubre (2002) and Universidad Metropolitana para la Educación y el Trabajo (2013). The group also operates Editorial Octubre publishing house, Caras y Caretas Sala cultural venue, and manages Sportivo Barracas football club.
