THE ROAD TO THE INTERNET

1945
Vannevar Bush (Science Advisor to Pres. Roosevelt during WWII) proposes MEMEX, a machine to store vast amounts of information.

1956
IBM develops the first hard disk: it was as big as two refrigerators and held 5MB of data.

1957
Sputnik I launched by USSR.

1958
Advanced Research Projects Agency (ARPA) formed in the Department of Defense.

1950s
Time-sharing, the concept of linking many users to a single computer by remote terminals, is developed in the late 1950s and early ’60s at MIT.

1961
Leonard Kleinrock publishes first paper on packet switching networks.

1962
Paul Baran of RAND develops the idea of distributed, packet-switching networks.

1965
Computers at MIT’s Lincoln Lab and System Development Corp. in Santa Monica, Calif., are directly linked in the first Wide Area Network. ARPA sponsors study on “cooperative network of time-sharing computers.”

1966
Bob Taylor at ARPA receives funding for a networking experiment to tie together computers at a number of universities.

1967
Wes Clark comes up with the idea of using dedicated hardware to perform network functions; the devices are eventually called Interface Message Processors (IMPs).

1968
ARPA mails 140 Requests for Proposals to prospective contractors to build the first four IMPs. Bolt Beranek and Newman (BBN) wins the contract to create ARPANET. They have $1 million and less than a year to turn the theory into a working system.

1969
BBN installs the first ARPANET IMP nodes at UCLA, Stanford Research Institute, UC Santa Barbara, and U of Utah using Honeywell 516 mini-computers with 12K of memory.

1970
ARPANET hosts start using Network Control Protocol (NCP).
ARPANET has 15 nodes (23 hosts). File Transfer Protocol (FTP) is established.

1971
Xerox PARC (Palo Alto Research Center) is established.

1971
BBN’s Ray Tomlinson ’63 “invents” e-mail; it quickly becomes the network’s most popular application.

1973
Bob Metcalfe outlines the idea for Ethernet in his Harvard Ph.D. thesis. He and David Boggs later create the first Ethernet network between computers named Michelson and Morley (19th c. scientists who proved ether didn’t exist) at Xerox PARC.

Xerox/Alto computer is built. (Some argue it was the first personal computer, although it was never offered for sale.) It had the first graphical user interface (GUI), used a mouse, and was linked to other PCs by Ethernet.

1974
Vint Cerf and Bob Kahn establish Transmission Control Protocol (TCP). They use the term Internet for the first time.

1975
The Altair 8800, generally recognized as the first PC, is invented by Bob Metcalfe at Xerox PARC. (It is actually a kit you have to build yourself.)
Microsoft is founded.

1977
The Apple II computer goes on the market.

1978
Vint Cerf, Steve Crocker, and Danny Cohen create a plan to separate the routing functions of TCP into a separate protocol called Internet Protocol (IP).

1981
IBM releases its IBM PC, retailing for $4,500.
Paul Severino ’69 founds InterLan, the first company to provide Ethernet adaptor products.

1982
TCP/IP are established as the standard protocol suite for ARPANET.
The first PC LAN is demonstrated at the National Computer Conference.

1983
The entire ARPANET switches from NCP to IP. Time magazine names its 1982 Man of the Year: the personal computer. ARPANET is split into military and civilian sections: the Internet is “born.”

Berkeley releases Unix 4.2BSD. It includes TCP/IP.
Internet hosts breaks 500. [Source for Internet host figures: Hobbes’ Internet Timeline]

Richard Mandelbaum ’65 co-founds NYSERNet, the first nongovernment ISP.

Martin Schoffstall ’82 creates SNMP (with 3 colleagues).

Severino sells Interlan to Micom Systems for $64 million.

1986
NSFNet is created to connect the supercomputing sites with a backbone speed of 56Kbps.

NSF-funded regional networks, including NYSERNet, SDSCNET, JVNCNET, and SURANET, become operational.

Severino founds Wellfleet Communications, named fastest-growing company in 1992 and ’93.

Jim Pelkey ’68 interviews Internet and computing pioneers.

1989
First gateways between commercial electronic mail carriers and the Internet are established: Compuserv through Ohio State University and MCI through the Corporation for the National Research Initiative.
