Computer-supported collaboration research focuses on technology that affect groups, organizations communities and societies, e.g. Wikipedia:voice mail, chat. It grew from cooperative work study of supporting people's work activities and working relationships. As net technology increasingly supported a wide range of recreational and social activities, consumer markets expanded the user base, more and more people were able to connect online to create what researchers have called a Computer Supported Cooperative World which includes "all contexts in which technology is used to mediate human activities such as communication, coordination, cooperation, competition, entertainment, games, art, and music." - from CSCW 2004
