The Internet as a publicly accessible World Wide Web was introduced by Tim Berners-Lee in 1991 and developed with the Mosaic (later Netscape) browser of 1992. However, the origins of the Internet date back much further to the Cold War period and "ARPAnet".
"ARPAnet" was an American response to the increasing threat of Russian missile strikes. It was reasoned in 1962, by J.C.R. Licklider, an M.I.T. and ARPA scientist, that a computer network would allow politicians and government agents to communicate if a Soviet strike destroyed the U.S. telephone system. In 1969, after the concept and system had been refined, the first message was delivered between UCLA and Stanford. It read simply as "LO", since the full message, "LOGIN", was too much for the network to handle.
The number of computers connected to the ARPAnet grew significantly after 1969 as it integrated machines from multiple countries.
In the late 1970s, computer scientist Vinton Cerf invented TCP (Transmission Control Protocol) to facilitate communication between the individual networks around the world, later adding the IP (Internet Protocol) to create the modern TCP/IP.
A decision in Congress that the Internet had great commercial potential eventually led to the e-commerce boom starting in 1992.Learn More
