"MEDIACITY: Situations, Practices and Encounters" investigates how the social settings and spaces of the city are created, experienced and practiced through the use and presence of new media. It takes the position that new media enables different settings, practices and behaviours to occur in urban space. Contributions from academics, practitioners and activists from disciplines such as Media Studies, Architecture, Urban Studies, Cultural and Urban Geography and Sociology present a critical reflection on the processes, methods and impacts of technologies in urban space.
