Basically it is made from computers and cables. The Web is an abstract (imaginary) space of information. On the Net, you find computers -- on the Web, you find document, sounds, videos, information. On the Net, the connections are cables between computers; on the Web, connections are hypertext links. The Web could not be without the Net.” -- Tim Berners Lee What were Tim Berners-Lee's original goals in creating the Web? The Internet : The Gold Rush Tim Berners-Lee: “We have to be careful because the sort of Web we end up with and the society we end up building on top of it will be determined by the decisions we make. All the decisions – the protocols we design within the consortium, the ways we implement them within companies, as well as the decisions people make when they browse – will shape the Web. … People have to be aware of this. We have the answers in our own hands.” .

I: the Conception
Excerpt from: Mayo, Keenan and Newcomb, Peter. “How the Web Was Won,” Vanity Fair, July 2008. I: The Conception Paul Baran, an electrical engineer, conceived one of the Internet’s building blocks—packet switching— while working at the Rand Corporation around 1960. Packet switching breaks data into chunks, or “packets,” and lets each one take its own path to a destination, where they are re-assembled (rather than sending everything along the same path, as a traditional telephone circuit does). A similar idea was proposed independently in Britain by Donald Davies. Later in his career, Baran would pioneer the airport metal detector. Paul Baran: It was necessary to have a strategic system that could withstand a first attack and then be able to return the favor in kind. The problem was that we didn’t have a survivable communications system, and so Soviet missiles aimed at U.S. missiles would take out the entire telephone- communication system. At that time the Strategic Air Command had just two forms of communication. One was the U.S. telephone system, or an overlay of that, and the other was high-frequency or shortwave radio. So that left us with the interesting situation of saying, Well, why do the communications fail when the bombs were aimed, not at the cities, but just at the strategic forces? And the answer was that the collateral damage was sufficient to knock out a telephone system that was highly centralized. Well, then, let’s not make it centralized. Let’s spread it out so that we can have other paths to get around the damage.

This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks. In 1982 the Internet Protocol Suite (TCP/IP) was standardized and the concept of a world-wide network of fully interconnected TCP/IP networks called the Internet was introduced.

Oral History of Elizabeth (Jake) Feinler Interviewed by: Marc Weber Recorded: September 10, 2009 Mountain View, California Editor’s note: Material in [square brackets] has been added by Jake Feinler CHM Reference number: X5378.2009 © 2009 Computer History Museum Oral History of Elizabeth (Jake) Feinler Marc Weber: I’m Marc Weber from the Computer History Museum, and I’m here today, September 10th, 2009, with “Jake” Elizabeth Feinler, who was the director of the Network Information Systems Center at SRI. [This group provided the Network Information Center (NIC) for the Arpanet and the Defense Data Network (DDN), a project for which she was the principal investigator from 1973 until 1991. Earlier she was a member of Douglas Engelbart’s Augmentation Research Center (ARC) at SRI [which [housed] the second computer on the Arpanet. It was on this computer that the NIC resided initially.] Jake is also a volunteer here at the museum. [She has donated an extensive collection of early Internet papers to the museum, and has been working on organizing this collection for some time.] Thank you for joining us. Elizabeth (Jake) Feinler: My pleasure. Weber: I really just wanted to start with where did you grow up and what got you interested in technical things or things related to this. Feinler: [Originally I hoped to pursue a career in advertising design, but could not afford the freshman room and board away from home, so I began attending West Liberty State College (now West Liberty University) close to my home. West Liberty was very small then, and the] art department [wasn’t very good.

These include early theoretical foundations, specifying original protocols, and expansion beyond a research tool to wide deployment. The pioneers Contents Claude Shannon The pioneers Claude Shannon Claude Shannon (1916–2001) called the "father of modern information Vannevar Bush theory", published "A Mathematical Theory of Communication" in J. C. R. Licklider 1948. His paper gave a formal way of studying communication channels. It established fundamental limits on the efficiency of Paul Baran communication over noisy channels, and presented the challenge of Donald Davies finding families of codes to achieve capacity.[1] Charles M. Herzfeld Bob Taylor Vannevar Bush Larry Roberts Leonard Kleinrock Vannevar Bush (1890–1974) helped to establish a partnership between Bob Kahn U.S. military, university research, and independent think tanks. He was Douglas Engelbart appointed Chairman of the National Defense Research Committee in Elizabeth Feinler 1940 by President Franklin D. Roosevelt, appointed Director of the Louis Pouzin Office of Scientific Research and Development in 1941, and from 1946 John Klensin to 1947, he served as chairman of the Joint Research and Development Vint Cerf Board. Out of this would come DARPA, which in turn would lead to the ARPANET Project.[2] His July 1945 Atlantic Monthly article "As We Yogen Dalal May Think" proposed Memex, a theoretical proto-hypertext computer Peter Kirstein system in which an individual compresses and stores all of their books, Steve Crocker records, and communications, which is then mechanized so that it may Jon Postel [3] be consulted with exceeding speed and flexibility.

Origin of Email & Misuses of the Term “Email”
Deborah J. Nightingale, Sen Song, Leslie P. Michelson, Robert Field Origin of Email & Misuses of the Term “Email” 2 Abstract: The origin of email, the system as we all know and use today, begins in 1978 when a 14-year-old Research Fellow, V.A. Shiva Ayyadurai, working at the University of Medicine and Dentistry of New Jersey (UMDNJ), located in New- ark, New Jersey, invented the first electronic system to replicate the interoffice, in- ter-organizational paper-based mail system consisting of Inbox, Outbox, Folders, Memo, Attachment, Address Book, etc. Ayyadurai named this system “email, ” a term he was the first to create, because he was inventing the “electronic” or “e” version of the interoffice, inter-organizational paper-based “mail” system. More- over, the specific naming of email arose for idiosyncratic reasons since FORTRAN IV, the programming language used to create his invention, required all variable and program names to be in upper case and a maximum of six charac- ters, while the Hewlett Packard RTE-IVB operating system, on which the software executed, had a five-character limit for program names. These constraints moti- vated the selection of “E,” “M,” “A,” “I,” and “L.” Prior to 1978, neither the term “email,” in any variation, upper case, lower case, mixed case, with or without the dash, nor did the software application “email” exist. After Ayyadurai’s invention, the term “email” was misused, primarily by members of the ARPANET communi- ty and Raytheon/BBN, to refer to their developments in rudimentary methods for exchanging text messages, done prior to 1978, as “email.” Such developments, while important in their own right, were not email, the system of interlocking parts intended to emulate the interoffice, inter-organizational paper-based mail system - -- the email we all experience today.

Legends Sasha Cavender, 10.05.98
Legends Sasha Cavender, 10.05.98 NEW YORK - RAY TOMLINSON CREATED SOMETHING BIG, but he is known for something very small. Sitting in his compact office in a bland building in Cambridge, Massachusetts, the inventor of email smiles at the idea that his name seems destined to be linked to the @ sign, the symbol used to introduce an email address. "I thought about other symbols, but @ didn't appear in any names, so it worked," he says. That was then. Now the sign is fast becoming a pop icon that signifies the hyperlinked communications of our time, ubiquitous on billboards and ads, company names (@Home), and even works of art, such as the ballet F@ust. Currently, more than 125 million people use the sign in their electronic addresses, an identifier that now means more to many of them than the numbers on their homes. Considering how profoundly Tomlinson's invention has changed the way we live and work, its beginnings were modest. After graduating from MIT in 1965, the young computer engineer spent two years working on a doctorate, then went to work nearby at Bolt Beranek and Newman (BBN), a company that had a government contract to work on the Arpanet, precursor of the Internet. "We were building an operating system to run on bargain-basement hardware," recalls his longtime friend and BBN colleague Jerry Burchfiel, "and Ray came up with a 'Send Message' program. It worked only on a local system at first, but then he took it further and created cross-Arpanet mail." Unlike Alexander Graham Bell's famous first call to his assistant, Watson, the content of the first email message -- from Tomlinson on one computer to himself on another -- is forgotten.
