and generated rapid growth as institutional, personal, and mobile computers were connected to the network.

By the late 2000s, its services and technologies had been incorporated into virtually every aspect of everyday life.

ARPANET development began with two network nodes which were interconnected between the Network Measurement Center at the University of California, Los Angeles (UCLA) Henry Samueli School of Engineering and Applied Science directed by Leonard Kleinrock, and the NLS system at SRI International (SRI) by Douglas Engelbart in Menlo Park, California, on 29 October 1969.
