His theoretical trilogy on ‘allegories of control’ – Protocol: How Control Exists After Decentralization (2004), Gaming: Essays on Algorithmic Culture (2006) and The Interface Effect (2012) – became foundational for Media and Software Studies, where he made an equally important contribution as a programmer and media artist. From 1996 to 2002 Galloway was associated with Rhizome, a New York based new media organisation, where he worked as editor and technical director. He also founded Radical Software Group (RSG), a collective of media artists named after Radical Software magazine, published between 1971 and 1974, which explored the impact of video and television on society, fought for the freedom of information and warned against the dangers of its corporate control.
