The Internet is a result of the following five main developments:
· First Computer Network: SAGE air defense system, Initiated by MIT in the early 1950s, built by many contractors and operational 1958-1982.
· General Purpose Interactive Computing: timesharing systems, developed at MIT, beginning operating in 1962 and went commercial in 1965.
· General Purpose Computer Networking, initiated by people from MIT and funded by the Defense Department’s Advanced Research Projects Agency (ARPA), resulting in the ARPANET, which largely interconnected academic institutions.
· Network Interconnections: Internet Protocols developed at Stanford University, released in 1974 and eventually adopted widely, forming the Internet. Also called TCP/IP.
· Standardized Graphical Terminal Interface: World-Wide-Web, started at CERN in Switzerland in 1990, came into widespread use by 2000 and now is maintained at MIT.
Thus, MIT played a major part in creating the Internet. By chance, Lester Earnest contributed to each of the above developments, and is evidently the only person in the world who did that.
