(Earlier) Milestones in Internet History

• 1961: Leonard Kleinrock writes the first paper on packet switched networks.
• 1962: J.C.R. Licklider of MIT writes a paper describing a globally connected "Galactic Network" of computers.
• 1966: Larry Roberts proposes the ARPANET to the Defense Department's Advanced Research Projects Agency (ARPA).
• 1968: ARPA issues Request for Quotations for the Interface Message Processors (IMPs), which became the first routers.
• 1969: First IMP is installed at UCLA. Early 1970s: Universities and defense agencies and contractors begin to connect to ARPANET.
• 1973: Bob Kahn and Vint Cerf begin research into what eventually becomes IP - the Internet Protocol and its companion, TCP - the Transmission Control Protocol.
• 1973: Bob Metcalfe develops Ethernet, which had been the subject of his PhD thesis, while working at Xerox.
• Early 1980s: The Personal Computer revolution begins.
• Mid 1980s: Local Area Networks (LANs) begin to flourish in business and university environments. Campus area networks soon follow.
• January 1, 1983: All "old-style" traffic on the ARPANET ceases, as TCP/IP becomes the only protocol used. [Arguably, this is the date of the birth of the Internet as a functioning, practical, production network.]
• 1985: Dennis Jennings chooses TCP/IP as the protocol for the planned National Science Foundation Network (NSFnet).
• 1988: NSF sponsors a series of workshops at Harvard on the commercialization and privatization of the Internet.
• 1988: Kahn et al. write a paper "Towards a National Research Network." According to the Brief History, "This report was influential on then Senator Al Gore, and ushered in high speed networks that laid the networking foundation for the future information superhighway."
• 1991: Mark McCahill et al. (University of Minnesota) release the Internet Gopher, the first widely-adopted menu-based system for browsing and retrieving Internet-based documents.
• 1991: Tim Berners-Lee et al. at the European Center for High-Energy Physics (CERN) describe the World Wide Web. The first browser is a line-mode tool.
• March 1993: Mark Andreessen et al. at the National Center for Supercomputing Applications (NCSA) at the University of Illinois release Mosaic, the first widely-adopted graphical browser for the Web
