Editing 1980s (section)

=== Information technology ===
* During the decade [[Microsoft]] released the operating systems '''[[MS-DOS]]''' (1981), '''[[Windows 1.0]]''' (1985), and '''[[Windows 2.0]]''' (1987).
* Mathematical Software [[MathLab]], introduced in 1988, by [[Stephen Wolfram]].
* The '''[[CD]]''' – the most basic CD ("Digital Audio Compact Disc") was released in October 1982 for distribution and listening to [[digital audio]], and at the time contained up to 74 minutes of music.
* '''[[TCP/IP]]''': [[ARPANET]] officially changed its main protocol from NCP to [[TCP/IP]] on 1 January 1983, when the new protocols were activated. The TCP/IP protocol will become the dominant communications protocol from then onwards, and would be used as the foundation on which the [[Internet]] would be based.
* The '''[[GNU Project]]''' (1983). The '''[[Free Software Foundation]]''' (1985).
* '''[[FidoNet]]''' – In 1984, FidoNet was launched, enabling [[Bulletin board system|BBS]] users to send private messages (e-mails) and public messages (in the forum) between all BBS systems that were connected to the FidoNet network, in addition to sending files to each other. The rise in popularity and availability of the Internet around the world around the mid-1990s eventually contributed to the irrelevance of FidoNet.
* '''[[World Wide Web]]''' – In 1989, the British computer scientist [[Tim Berners-Lee]] first proposed a project to his employer [[CERN]], based on the concept of [[hypertext]], to facilitate sharing and updating information among researchers. In mid-November 1989 he would develop the first successful communication between a [[Hypertext Transfer Protocol]] (HTTP) client and server via the [[internet]]. In the coming years Berners-Lee developed the system which would later become the foundation of the [[World Wide Web]].
