ABSTRACT
As technologies change, the forms of CMC evolve. Sometimes there is divergence, for example, the newer audiovisual possibilities to contrast with the purely text-based, while in other aspects there is convergence, as in the amalgamation of many forms within a single Web-browser environment. Some forms of CMC are purely synchronous, some purely asynchronous, while others (e.g., NetMeetingTM, ICQTM) are now allowing the two to occur in the same environment.
