Institut Municipal d’Informàtica (IMI) is the institution related to computer management at the Municipality of Barcelona. For its 50th anniversary, the city decided to carry on a project to regain the history & memories of the unit. On behalf of it, more than 30 personal and group interviews were conducted, with different workers and profiles, some of them already retired. The task made possible to gain many points of view and enrich its path story. The final result was reflected into various audiovisual pieces of short duration, as a testimony of the history of the institution.
