Computer-mediated communication (CMC) is an umbrella term that encompasses various forms of human communication through networked computers, which can be synchronous or asynchronous and involve one-to-one, one-to-many, or many-to-many exchanges of text, audio, and/or video messages. Early research has focused largely on how mediation by technology alters the processes and outcomes of social interaction and group processes, addressing issues such as how people express and construe self-identity, form and manage impressions, develop and maintain relationships, build communities, collaborate at a distance and make collective decisions, mostly in contrast to non-mediated, face-to-face communication. As such, core theories that guided earlier studies highlight the dearth of socio-contextual information as the defining characteristic of CMC working to its disadvantage. However, they were soon challenged by alternative models underscoring individual users’ active accommodation to the limited channel capacity and even more strategic appropriation of the constraints of the medium. In a similar vein, the dichotomous view that differentiates the “real” from the “virtual” gradually was replaced by the perspective that underscores the blurring boundary and the fluid interaction between the two. At the same time, researchers have also investigated who turns to online communication as opposed to offline, face-to-face interaction, and with what consequences. Going beyond dyadic interaction between unacquainted individuals, social and psychological implications of CMC have also been examined in various contexts, such as distributed workgroups (computer-supported cooperative work: CSCW), social network sites (SNSs), and online games.
