In what year was the Internet invented?
the internet started in 1957 DARPA was created in 1958. But this only started the research that led to create the Internet. The Network Control Protocol (NCP) was finalized and deployed in December 1970 by the Network Working Group (NWG), led by Steve Crocker. But it was not until RFC 768 "User Datagram Protocol", RFC 791 "Internet Protocol", RFC 792 "Internet Control Message Protocol, RFC 793 "Transmission Control Protocol" were ratified in 1980 and 1981 that the Internet took shape. Modern protocols like e-mail, ftp, telnet, http ... all depend on these underlying protocols. The ARPANET host protocol was switched from NCP to TCP/IP as of January 1, 1983. The underlying protocols that run the Internet have fundamentally changed since this date. Much later on Mar. 11, 1999 Al Gore claims to have invented the Internet: "During my service in the United States Congress, I took the initiative in creating the Internet."
