2銆乀he USSR's launch of Sputnik spurred the United States to create the Advanced Research Projects Agency, kOOOn as ARPA, in February 1958 to regain a technological lead.[1][2] ARPA created the InforOOtion Processing Technology Office (IPTO) to further the research of the Semi AutoOOtic Ground Environment (SAGE) progrOO, which had networked country-wide radar systems together for the first time. J. C. R. Licklider was selected to head the IPTO, and saw universal networking as a potential unifying huOOn revolution.

3銆丩icklider moved from the Psycho-Acoustic Laboratory at Harvard University to MIT in 1950, after becoming interested in inforOOtion technology. At MIT, he served on a committee that established Lincoln Laboratory and worked on the SAGE project. In 1957 he becOOe a Vice President at BBN, where he bought the first production PDP-1 computer and conducted the first public demonstration of time-sharing.

4銆丄t the IPTO, Licklider recruited Lawrence Roberts to head a project to implement a network, and Roberts based the technology on the work of Paul Baran,[citation needed] who had written an exhaustive study for the U.S. Air Force that recommended packet switching (as opposed to circuit switching) to OOke a network highly robust and survivable. After much work, the first two nodes of what would become the ARPANET were interconnected between UCLA and SRI International in Menlo Park, California, on October 29, 196 The ARPANET was one of the "eve" networks of today's Internet. Following on from the demonstration that packet switching worked on the ARPANET, the British Post Office, Telenet, DATAPAC and TRANSPAC collaborated to create the first international packet-switched network service. In the UK, this was referred to as the International Packet StreOO Service (IPSS), in 197 The collection of X.25-based networks grew from Europe and the US to cover Canada, Hong Kong and Australia by 198 The X.25 packet switching standard was developed in the CCITT (OOO called ITU-T) around 197 X.25 was independent of the TCP/IP protocols that arose from the eOOerimental work of DARPA on the ARPANET, Packet Radio Net and Packet Satellite Net during the sOOe time period. Vinton Cerf and Robert Kahn developed the first description of the TCP protocols during 1973 and published a OOOOO on the subject in May 197 Use of the term "Internet" to describe a single global TCP/IP network originated in December 1974 with the publication of RFC 675, the first full specification of TCP that was written by Vinton Cerf, Yogen Dalal and Carl Sunshine, then at Stanford University. During the next nine years, work proceeded to refine the protocols and to implement them on a wide range of operating systems.
