Invention of Internet

29 October 1969

The Internet grew from ARPANET, a research network funded by the United States Defense Advanced Research Projects Agency. In late October 1969 a message was sent between computers at the University of California, Los Angeles, and the Stanford Research Institute, and the system crashed after the first two letters of the intended word login had been transmitted. Over the next years the network added more universities and research centres, and email appeared in 1971. The decisive step came when Vinton Cerf and Robert Kahn developed the TCP/IP protocols, which ARPANET adopted on 1 January 1983 and which allowed separate networks to be linked into a single internet. Tim Berners-Lee's World Wide Web, created at CERN from 1989 and released in 1991, then made the network accessible to the general public.
