Licklider, the first director of the Information Processing Techniques Office (IPTO) at The Pentagon's ARPA, used the term in the early 1960s to refer to a networking system he "imagined as an electronic commons open to all, 'the main and essential medium of informational interaction for governments, institutions, corporations, and individuals.
'"[2][3] An office memorandum he sent to his colleagues in 1963 was addressed to "Members and Affiliates of the Intergalactic Computer Network".
[4] As head of IPTO from 1962 to 1964, "Licklider initiated three of the most important developments in information technology: the creation of computer science departments at several major universities, time-sharing, and networking.
"[3] Licklider first learned about time-sharing from Christopher Strachey at the inaugural UNESCO Information Processing Conference in Paris in 1959.
[5] By the late 1960s, his promotion of the concept had inspired a primitive version of his vision called ARPANET.
