Promoted to the head of the information processing office at
DARPA, Robert Taylor intended to realize Licklider's ideas of an interconnected networking system. Bringing in
Larry Roberts from MIT, he initiated a project to build such a network. The first ARPANET link was established between the
University of California, Los Angeles and the
Stanford Research Institute on 22:30 hours on
October 29,
1969. By
5 December 1969, a 4-node network was connected by adding the
University of Utah and the
University of California, Santa Barbara. Building on ideas developed in
ALOHAnet, the ARPANET grew rapidly. By 1981, the number of hosts had grown to 213, with a new host being added approximately every twenty days.

ARPANET became the technical core of what would become the Internet, and a primary tool in developing the technologies used.
