(ZDNet, Cambridge, MA, www.zdnet.com) A technical portal for PC users from CNET Networks, Inc. (www.cnetnetworks.com). ZDNet contains news, white papers, product reviews and links to a wide variety of shareware, trial downloads and public domain software on the Internet.

ZDNet dates back to PCMagNet, the Ziff-Davis PC Magazine bulletin board, launched in 1985 as a service on CompuServe. It was renamed ZiffNet and also made available on Prodigy and its own service. Renamed ZDNet, it evolved to the Web as did most online services of the era. CNET acquired ZDNet from Ziff Davis Media in 2000. See Ziff Davis Enterprise and Ziff Davis Media.
