The Junge Gesellschaft zur Förderung der Kunst und Medientechnologie e. V. Hamburg (Young Society for the Promotion of Art and Media Technology e. V. Hamburg) is listed in the credits of all Piazza virtuale broadcasts as the production company. The association was founded in 1988 by Salvatore Vanasco, Mike Hentz, Benjamin Heidersberger and Karel Dudesek in order to be able to take advantage of its “Eingetragener Verein (e. V.)” status (registered voluntary association). This  confers many legal benefits, and such a organization can apply for the status of a charitable organization (“Gemeinnützigkeit”). Most likely for similar purposes, an Verein zur Förderung des interaktiven Fernsehens e.V. (Association for the Promotion of Interactive Television) was founded first in Hamburg and then in Hanover in the following years.
It was founded after all the group members had taken permanent residence in Hamburg, whereas before the the group members moved between different cities including Düsseldorf, Frankfurt, Wolfsburg, Berlin, Vienna and Zurich. Not only for Piazza virtuale, but also on other occasions, the Verein received public funding, for which a commercial entity would not have been entitled to. In contrast, Ponton was organised as a Gesellschaft bürgerlichen Rechts (Public Partnership).
