Timeline: History of the Internet
1. 1962
•J.C.R. Licklider writes memos about his Intergalactic Network concept, where everyone on the globe is interconnected and can access
programs and data at any site from anywhere. He is talking to his own ‘Intergalactic Network’ of researchers across the country.
1963
•A joint industry-government committee develops ASCII (American Standard Code for Information Interchange), the first universal standard for computers.
It permits machines from different manufacturers to exchange data.
1965
•DEC unveils the PDP-8, the first commercially successful minicomputer. Small enough to sit on a desktop, it sells for $18,000 — one-fifth
the cost of a low-end IBM/360 mainframe.
1967 Larry Roberts puts together his plan for the ARPANET
1968 Roberts and the ARPA team refine the overall structure and specifications for the ARPANET. They issue an RFQ for the
development of the IMPs
1969 Nodes are added to the ARPANET at the rate of one per month.
2. 1973
Thirty institutions are connected to the ARPANET. The network users range from industrial installations and consulting firms
like BBN, Xerox PARC and the MITRE Corporation, to government sites like NASA’s Ames Research Laboratories, the National
Bureau of Standards, and Air Force research facilities.
1977
•Steve Wozniak and Steve Jobs announce the Apple II computer. Also introduced are the Tandy TRS-80 and the Commodore Pet. These
three off-the-shelf machines create the consumer and small business markets for computers.
1981
•By the beginning of the year, more than 200 computers in dozens of institutions have been connected in CSNET. BITNET, another startup
network, is based on protocols that include file transfer via e-mail rather than by the FTP procedure of the ARPA protocols.
1983 In January, the ARPANET standardizes on the TCP/IP protocols adopted by the Department of Defense (DOD). The
Defense Communications Agency decides to split the network into a public ‘ARPANET’ and a classified ‘MILNET, ‘ with only
45 hosts remaining on the ARPANET. Jon Postel issues an RFC assigning numbers to the various interconnected nets. Barry
Leiner Vint Cerf’s place at DARPA, managing the Internet.
1984 In January, Apple announces the Macintosh. Its user-friendly interface swells the ranks of new computer users.
1990 ARPANET formally shuts down. In twenty years, ‘the net’ has grown from 4 to over 300,000 hosts. Countries
connecting in 1990 include Argentina, Austria, Belgium, Brazil, Chile, Greece, India, Ireland, South Korea, Spain, and
Switzerland.
1998 . US Depart of Commerce outlines proposal to privatize DNS. ICANN created by Jon Postel to oversee privatization. Jon
Postel dies.
3. 2000
•. Fixed wireless, high-speed Internet technology is now seen as a viable alternative to copper and fiber optic lines
placed in the ground.
2001 . First uncompressed real-time gigabit HDTV transmission across a wide-area IP network takes
place on Internet2.
2006 . There are an estimated 92 million Web sites online
2007
•. Search engine giant Google surpasses Microsoft as "the most valuable global brand," and also is the most visited Web
site.
