This article examines the 'digital city' debate of the mid 1990s as a point of departure for a media-historical questioning of how technology and the discourse about technology were used as an experimental playground for new forms of knowledge that are fundamental for the understanding of today’s network society. This text has been presented as a conference paper at the 'networks and sustainability' track of the 'textiles' conference in Riga in June 2010. The paper will also appear in a special edition of the Arts and Communications Journal edited by RIXC at the end of 2010.
