Lévy, Pierre. Cyberculture. Electronic Mediations, V. 4. Minneapolis, Minn.; London: University of Minnesota Press, 2001.
Having had varying amounts of confusion defining certain elements and categorizations of the online video conversation (OVC), such as whether it is a medium, a method of communication, a genre, etc., I have found in Cyberculture an excellent approach to splitting and defining some of the terms I have used in the past. I’ve listed Lévy’s definitions (from Table 1 on page 46) below and placed the OVC within them.
