The Malvinas War, also known in Spanish as the South Atlantic Conflict (conflicto del Atlántico Sur), was a war between Argentina and the United Kingdom that took place in the Malvinas Islands, South Georgia, and South Sandwich between April 2 and June 14, 1982. During 2012, thirty years after the conflict, the Malvinas/30 web documentary was produced in Argentina, conceived as a transmedia production in real time. It was designed to serve as a space of collective digital memory that would involve users and recreate on social networks the hostile atmosphere of the South Atlantic Islands at the time of the skirmish. The documentary, produced by an interdisciplinary team, was developed as a continuous interactive production for five months that, by extending its narrative through different digital platforms, sought to allow users to relive the events of the Malvinas War as they had occurred three decades before in 1982. To meet this goal, Malvinas/30 was organized along three central axes: narrative synchronization between past and present (telling the story as if it were happening today); unfolding the story on different media (social networks, traditional media, and other media); and generating interactive responses from users (a collective story as a space for historical memory).
