The World Wide Web (abbreviated as WWW or W3,[1] commonly
known as the web) is a system of interlinked hypertext documents that run on
and are accessed via the Internet. With a web browser, one can view web pages
that may contain text, images, videos, and other multimedia and navigate
between them via hyperlinks.
Tim Berners-Lee, a British computer scientist and former
CERN employee,[2] is considered the inventor of the web.[3] On March 12,
1989,[4] he wrote a proposal for what would eventually become the World Wide
Web.[5] The 1989 proposal was meant for a more effective CERN communication
system but Berners-Lee eventually realised the concept could be implemented
throughout the world.[6] Berners-Lee and Belgian computer scientist Robert
Cailliau proposed in 1990 to use hypertext "to link and access information
of various kinds as a web of nodes in which the user can browse at
will",[7] and Berners-Lee finished the first website in December of that
year.[8] The first test was completed around 20 December 1990 and Berners-Lee
reported about the project on the newsgroup alt.hypertext on 7 August 1991.[9]
