 He was a member of the editorial board of the "Revue virtuelle" project of the Pompidou Center in Paris from 1995 to 1997 and was the author of a report on cyberculture for the Council of Europe in 1996.In the chapter Interactivity from his book "Cyberculture" (2001), Lévy argues that analogue communication (telephone, mail) differs from digital communication (email, chat) in terms of temporal organization and material involvement of their communication systems.He claims that interactivity is a vague term that "has more to do with finding the solution to a problem, the need to develop new ways to observe, design, and evaluate methods of communication, than it does with identifying a simple, unique characteristic that can be assigned to a given system".
