From Computer-mediated communication: "Computer-Mediated Communication (CMC) is defined as any communicative transaction which occurs through the use of two or more networked computers.[1] While the term has traditionally referred to those communications that occur via computer-mediated formats (i.e., instant messages, e-mails, chat rooms) it has also been applied to other forms of text-based interaction such as text messaging. ... Popular forms of CMC include e-mail, video, audio or text chat (text conferencing including "instant messaging"), bulletin boards, list-servs and MMOs. These settings are changing rapidly with the development of new technologies. Weblogs (blogs) have also become popular, and the exchange of RSS data has better enabled users to each "become their own publisher."
