APSI (an abbreviation of "Agencia Publicitaria de Servicios Informativos") was a magazine aimed as means of political opposition to the Pinochet dictatorship. It was started with a grant obtained in Belgium by Cristián Precht, an employee of the Vicariate of Solidarity. Due to the climate of censorship in Chile the magazine focused initially on international news. APSI was published with support of the Popular Unitary Action Movement until late 1978. In 1979 the magazine begun reporting on local issues including the numerous human rights violations of the dictatorship.
