"In 1947 Father José Joaquín Salcedo laid the cornerstone of what would become, until its demise nearly a half century later, Latin America’s largest, Catholic, mass media-based education and community development network, the Radiophonic Schools of Radio Sutatenza and Acción Cultural Popular (ACPO). Begun as an experiment in rural catechetical outreach using a homemade radio transmitter, three borrowed receivers, and an old film projector, the radiophonic school system expanded to encompass five radio stations, state-of-the-art printing and recording facilities, a national circulation newspaper aimed exclusively at rural readers, and Latin America’s first leadership training institutes for peasants."
