Since 2008, the GVU has performed annually the so-called ROOF-industry forum together with VAP and SAFE, which recently took place in the Kalkscheune venue in Berlin. At the event, lawyers, representatives of the games and movie industries are brought together with trade associations and other stakeholders under the slogan "prevention and education". In 2011, the study of digital content usage (short DCN study) received large attention, since it was the first to cover the specific uses of legal and illegal online content. The study was prepared by the GVU and the Bundesverband Musikindustrie (Federal Association of Music Industry) as well as the Börsenverein des Deutschen Buchhandels (Association of German Book Trade).
