The term Silicon Valley was coined by Ralph Vaerst, a Northern California entrepreneur. Its first published use is credited to Don Hoefler, a friend of Vaerst's, who used the phrase as the title of a series of articles in the weekly trade newspaper Electronic News. Don C Hoefler (c 1922 - April 15, 1986) is an American Journalist who coined the term " Silicon Valley " A newspaper is a written Publication containing News, information and Advertising, usually printed on low-cost paper called Newsprint. Electronic News is an online publication that currently covers just the semiconductor production equipment industry The series, entitled "Silicon Valley USA," began in the paper's issue dated January 11, 1971. Events 1055 - Theodora is crowned Empress of the Byzantine Empire. Year 1971 ( MCMLXXI) was a Common year starting on Friday (link will display full calendar of the 1971 Gregorian calendar. Valley refers to the Santa Clara Valley, located at the southern end of San Francisco Bay, while Silicon refers to the high concentration of companies involved in the semiconductor and computer industries that were concentrated in the area. See Silicon Valley for a discussion of the technological aspects of the Santa Clara Valley San Francisco Bay is a shallow productive Estuary through which water draining from approximately forty percent of California, flowing in the Sacramento Silicon (ˈsɪlɪkən or /ˈsɪlɪkɒn/ silicium is the Chemical element that has the symbol Si and Atomic number 14 A semiconductor' is a Solid material that has Electrical conductivity in between a conductor and an insulator; it can vary over that A computer is a Machine that manipulates data according to a list of instructions. These firms slowly replaced the orchards which gave the area its initial nickname, the Valley of Heart's Delight. An orchard is an intentional planting of Trees or Shrubs maintained for Food production.
Perhaps the strongest thread that runs through the Valley’s past and present is the drive to “play” with novel technology, which, when bolstered by an advanced engineering degree and channeled by astute management, has done much to create the industrial powerhouse we see in the Valley today. [1]
Since the early twentieth century, Silicon Valley has been home to a vibrant, growing electronics industry. The industry began through experimentation and innovation in the fields of radio, television, and military electronics. Stanford University, its affiliates, and graduates have played a major role in the evolution of this area. Leland Stanford Junior University, commonly known as Stanford University or simply Stanford, is a private Research university located in
The San Francisco Bay Area had long been a major site of U.S. Navy research and technology. The San Francisco Bay Area, commonly known as the Bay Area, or the Bay, is a geographically and ethnically diverse metropolitan region that surrounds the In 1909, Charles Herrold started the first radio station in the United States with regularly scheduled programming in San Jose. Charles David 'Doc' Herrold, ( November 16, 1875 – July 1, 1948) was an American Radio broadcasting Radio is the transmission of signals by Modulation of electromagnetic waves with frequencies below those of visible Light. Later that year, Stanford University graduate Cyril Elwell purchased the U. Leland Stanford Junior University, commonly known as Stanford University or simply Stanford, is a private Research university located in S. patents for Poulsen arc radio transmission technology and founded the Federal Telegraph Corporation (FTC) in Palo Alto. The arc converter, sometimes called the arc transmitter or Poulsen arc after its inventor Valdemar Poulsen, is a device used to convert DC energy Over the next decade, the FTC created the world's first global radio communication system, and signed a contract with the U. S. Navy in 1912. [1]
In 1933, Air Base Sunnyvale, California was commissioned by the United States Government for the use as a Naval Air Station (NAS) to house the airship USS Macon in Hangar One. Two ships of the United States Navy have borne the name USS Macon, named in honor of the city of Macon Georgia. The station was renamed NAS Moffett Field, and between 1933 and 1947, US Navy blimps were based here. Moffett Federal Airfield, also known as Moffett Field, is a joint civil-military Airport located 3 miles (5 km north of Mountain View, in Santa [2] A number of technology firms had set up shop in the area around Moffett to serve the Navy. When the Navy gave up its airship ambitions and moved most of its West Coast operations to San Diego, NACA (the National Advisory Committee for Aeronautics, forerunner of NASA) took over portions of Moffett for aeronautics research. The National Aeronautics and Space Administration ( NASA, ˈnæsə is an agency of the United States government, responsible for the nation's public space program Aeronautics (from Greek aero which means air or sky and nautis which means sailor i Many of the original companies stayed, while new ones moved in. The immediate area was soon filled with aerospace firms such as Lockheed. This article is about the field of research and industry for the corporation see The Aerospace Corporation Aerospace comprises the The Lockheed Corporation (originally Loughead Aircraft Manufacturing Company was an American aerospace company founded in 1912 which merged with Martin Marietta
After World War II, universities were experiencing enormous demand due to returning students. To address the financial demands of Stanford's growth requirements, and to provide local employment opportunities for graduating students, Frederick Terman proposed the leasing of Stanford's lands for use as an office park, named the Stanford Industrial Park (later Stanford Research Park). Frederick Emmons Terman (June 7 1900 in English, Indiana – December 19 1982 was an American academic Stanford Research Park is a Technology park located in Palo Alto California on land owned by Stanford University. Stanford Research Park is a Technology park located in Palo Alto California on land owned by Stanford University. Leases were limited to high technology companies. Its first tenant was Varian Associates, founded by Stanford alumni in the 1930s to build military radar components. Varian Associates was a company founded in 1948 by Russell H and Sigurd F However, Terman also found venture capital for civilian technology start-ups . Venture capital (also known as VC or Venture) is a type of Private equity capital typically provided to immature high-potential growth companies One of the major success stories was Hewlett-Packard. Founded in Packard's garage by Stanford graduates William Hewlett and David Packard, Hewlett-Packard moved its offices into the Stanford Research Park slightly after 1953. Packard's garage, is a Museum where Hewlett-Packard was founded William Redington Hewlett ( May 20, 1913 &ndash January 12, 2001) was the co-founder with David Packard, of the Hewlett-Packard David Packard (September 7 1912 &ndash March 26 1996 was a co-founder of Hewlett-Packard (1939 serving as president (1947-1964 CEO (1964-1968 and Chairman of the In 1954, Stanford created the Honors Cooperative Program to allow full-time employees of the companies to pursue graduate degrees from the University on a part-time basis. The initial companies signed five-year agreements in which they would pay double the tuition for each student in order to cover the costs. Hewlett-Packard has become the largest personal computer manufacturer in the world, and transformed the home printing market when it released the first ink jet printer in 1984. Inkjet printers operate by propelling variably-sized droplets of liquid or molten material ( Ink) onto almost any sized page In addition, the tenancy of Eastman Kodak and General Electric undoubtedly made Stanford Industrial Park a center of technology in the mid-1990's. [3][4]
In 1953, William Shockley left Bell Labs in a disagreement over the handling of the invention of the transistor. William Bradford Shockley ( February 13, 1910 &ndash August 12, 1989) was a British -born American Physicist Bell Laboratories (also known as Bell Labs and formerly known as AT&T Bell Laboratories and Bell Telephone Laboratories) is the Research organization In Electronics, a transistor is a Semiconductor device commonly used to amplify or switch electronic signals After returning to California Institute of Technology for a short while, Shockley moved to Mountain View, California in 1956, and founded Shockley Semiconductor Laboratory. The California Institute of Technology (commonly referred to as Caltech) is a private, Coeducational research university located in Pasadena Shockley Semiconductor Laboratory was the first company to work on silicon semiconductor devices in what came to be known as Silicon Valley. Unlike many other researchers who used germanium as the semiconductor material, Shockley believed that silicon was the better material for making transistors. Germanium (dʒɚˈmeɪniəm is a Chemical element with the symbol Ge and Atomic number 32 Shockley intended to replace the current transistor with a new three-element design (today known as the Shockley diode), but the design was considerably more difficult to build than the "simple" transistor. In 1957, Shockley decided to end research on the silicon transistor. As a result, eight engineers left the company to form Fairchild Semiconductor. The Traitorous Eight, as they would become known are eight men who left Shockley Semiconductor Laboratory to form Fairchild Semiconductor in 1957. Present day Fairchild Semiconductor International Inc is a spin-off company resulting from reconstitution of assets in National Semiconductor Two of the original employees of Fairchild Semiconductor, Robert Noyce and Gordon Moore, would go on to found Intel. Robert Norton Noyce ( December 12, 1927 &ndash June 3, 1990) nicknamed " the Mayor of Silicon Valley " co-founded Gordon Earle Moore (born 3 January 1929 in San Francisco, California) is the co-founder and Chairman Emeritus of Intel Corporation and the author [5]
By the early 1970s there were many semiconductor companies in the area, computer firms using their devices, and programming and service companies serving both. This article is about the Decade 1970-1979 For the Year 1970 see 1970. A semiconductor' is a Solid material that has Electrical conductivity in between a conductor and an insulator; it can vary over that A computer is a Machine that manipulates data according to a list of instructions. Industrial space was plentiful and housing was still inexpensive. The growth was fueled by the emergence of the venture capital industry on Sand Hill Road, beginning with Kleiner Perkins in 1972; the availability of venture capital exploded after the successful $1. Venture capital (also known as VC or Venture) is a type of Private equity capital typically provided to immature high-potential growth companies Sand Hill Road is a Road in Menlo Park California, notable for the concentration of Venture capital companies there Kleiner Perkins Caufield & Byers (KPCB is a Venture capital firm located on Sand Hill Road in Silicon Valley. 3 billion IPO of Apple Computer in December 1980.

Although semiconductors are still a major component of the area's economy, Silicon Valley has been most famous in recent years for innovations in software and Internet services. The Internet is a global system of interconnected Computer networks Silicon Valley has significantly influenced computer operating systems, software, and user interfaces.
Using money from NASA and the U.S. Air Force, Doug Engelbart invented the mouse and hypertext-based collaboration tools in the mid-1960s, while at Stanford Research Institute (now SRI International). Dr Douglas C Engelbart (born January 30 1925 is an American Inventor. In Computing, a mouse (plural mice, mouse devices, or mouses) SRI International, based in the United States is one of the world's largest contract Research institutes. When Engelbart's Augmentation Research Center declined in influence due to personal conflicts and the loss of government funding, Xerox hired some of Engelbart's best researchers. Stanford Research Institute 's Augmentation Research Center (ARC was founded by electrical engineer Douglas Engelbart to develop and experiment with new tools Xerox Corporation ( (name ˈziːrɒks is a global document management company which manufactures and sells a range of color and black-and-white printers, multifunction In turn, in the 1970s and 1980s, Xerox's Palo Alto Research Center (PARC) played a pivotal role in object-oriented programming, graphical user interfaces (GUIs), Ethernet, PostScript, and laser printers. PARC (Palo Alto Research Center Inc formerly Xerox PARC, is a Research and development company in Palo Alto California that began as a division of Object-oriented programming (OOP is a Programming paradigm that uses " objects " and their interactions to design applications and computer programs Ethernet is a family of frame -based Computer networking technologies for Local area networks (LANs PostScript ( PS) is a dynamically typed concatenative Programming language created by John Warnock and Charles Geschke in 1982 A laser printer is a common type of Computer printer that rapidly produces high quality text and graphics on plain paper
While Xerox marketed equipment using its technologies, for the most part its technologies flourished elsewhere. The diaspora of Xerox inventions led directly to 3Com and Adobe Systems, and indirectly to Cisco, Apple Computer and Microsoft. Adobe Systems Incorporated (pronounced a-DOE-bee əˈdoʊbiː ( is an American Computer software company headquartered in San Jose California Apple Inc, ( formerly Apple Computer Inc, is an American Multinational corporation with a focus on designing and manufacturing Consumer electronics Microsoft Corporation is an American multinational Computer technology Corporation, which rose to dominate the Home computer Apple's Macintosh GUI was largely a result of Steve Jobs' visit to PARC and the subsequent hiring of key personnel. Macintosh, commonly nicknamed Mac is a Brand name which covers several lines of Personal computers designed developed and marketed by Apple Inc Steven Paul Jobs (born February 24 1955 is the Co-founder, Chairman, and CEO of Apple Inc and former CEO of Pixar Animation Microsoft's Windows GUI is based on Apple's work, more or less directly. [6] Cisco's impetus stemmed from the need to route a variety of protocols over Stanford's campus Ethernet.
Silicon Valley is generally considered to have been the center of the dot-com bubble which started from the mid-1990s and collapsed after the NASDAQ stock market began to decline dramatically in April of 2000. The " dot-com bubble " (or sometimes the " IT bubble " was a speculative bubble covering roughly 1995–2001 (with a climax on March 10 The NASDAQ (acronym of National Association of Securities Dealers Automated Quotations) is an American Stock exchange. A stock market, or (equity market is a private or public market for the trading of company Stock and derivatives of company During the bubble era, real estate prices reached unprecedented levels. For a brief time, Sand Hill Road was home to the most expensive commercial real estate in the world, and the booming economy resulted in severe traffic congestion. Sand Hill Road is a Road in Menlo Park California, notable for the concentration of Venture capital companies there
Even after the dot-com crash, Silicon Valley continues to maintain its status as one of the top research and development centers in the world. A 2006 Wall Street Journal story found that 13 of the 20 most inventive towns in America were in California, and 10 of those were in Silicon Valley. [7] San Jose led the list with 3,867 utility patents filed in 2005, and number two was Sunnyvale, at 1,881 utility patents. [8]
