Etymology

The word "silicon" in the name originally referred to the large number of innovators and manufacturers in the region specializing in silicon-based transistors and integrated circuit chips. The popularization of the name is credited to Don Hoefler. He first used it in the article "Silicon Valley USA", which appeared in the January 11, 1971, issue of the weekly trade newspaper '' Electronic News''. However, the term did not gain widespread use until the early 1980s, at the time of the introduction of the IBM PC and numerous related hardware and software products to the consumer market.


History

Role of Stanford University

Stanford University, its affiliates, and graduates have played a major role in the development of this area. A very powerful sense of regional solidarity accompanied the rise of Silicon Valley. From the 1890s, Stanford University's leaders saw its mission as service to the (American) West and shaped the school accordingly. At the same time, the perceived exploitation of the West at the hands of eastern interests fueled booster-like attempts to build self-sufficient local industry. Thus regionalism helped align Stanford's interests with those of the area's high-tech firms for the first fifty years of Silicon Valley's development. Frederick Terman, as Stanford University's dean of the school of engineering from 1946, encouraged faculty and graduates to start their own companies. In 1951 Terman spearheaded the formation of Stanford Industrial Park (now Stanford Research Park, an area surrounding

After World War II, universities experienced enormous demand due to returning students. In 1951, to address the financial demands of Stanford's growth requirements, and to provide local employment-opportunities for graduating students, Frederick Terman proposed leasing Stanford's lands for use as an office park named the Stanford Industrial Park (later Stanford Research Park). Leases were limited to high-technology companies. The first tenant was

, Hewlett-Packard moved its offices into the Stanford Research Park shortly after 1953. In 1954 Stanford originated 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 thermal drop-on-demand ink-jet printer in 1984. Other early tenants included Eastman Kodak, General Electric, and Lockheed.

Emergence of venture capital

By the early 1970s, there were many semiconductor companies in the area, computer firms using their devices, and programming and service companies serving both. Industrial space was plentiful and housing was still inexpensive. Growth during this era was fueled by the emergence of venture capital on Sand Hill Road, beginning with Kleiner Perkins and Sequoia Capital in 1972; the availability of venture capital exploded after the successful $1.3 billion IPO of Apple Computer in December 1980. Since the 1980s, Silicon Valley has been home to the largest concentration of venture capital firms in the world. In 1971, Don Hoefler traced the origins of Silicon Valley firms, including via investments from Fairchild's eight co-founders.A Legal Bridge Spanning 100 Years: From the Gold Mines of El Dorado to the "Golden" Startups of Silicon Valley

More traditional industries also recognize the potential of high-tech development, and several car manufacturers have opened offices in Silicon Valley to capitalize on its entrepreneurial ecosystem. Manufacture of transistors is, or was, the core industry in Silicon Valley. The production workforce was for the most part composed of Asian and Latino immigrants who were paid low wages and worked in hazardous conditions due to the chemicals used in the manufacture of integrated circuits. Technical, engineering, design, and administrative staffs were in large part well compensated.

Housing

Silicon Valley has a severe housing shortage, caused by the market imbalance between jobs created and housing units built: from 2010 to 2015, many more jobs have been created than housing units built. (400,000 jobs, 60,000 housing units) This shortage has driven home prices extremely high, far out of the range of production workers. As of 2016 a two-bedroom apartment rented for about $2,500 while the median home price was about $1 million. The ''

'' called Silicon Valley the most expensive U.S. housing region. Homelessness is a problem with housing beyond the reach of middle-income residents; there is little shelter space other than in San Jose which, as of 2015, was making an effort to develop shelters by renovating old hotels. '' The Economist'' also attributes the high cost of living to the success of the industries in this region. Although, this rift between high and low salaries is driving many residents out who can no longer afford to live there. In the Bay Area, the number of residents planning to leave within the next several years has had an increase of 35% since 2016, from 34% to 46%.

reported that a third of Silicon Valley scientists and engineers were immigrants and that nearly a quarter of Silicon Valley's high-technology firms since 1980 were run by Chinese (17 percent) or Indian descent CEOs (7 percent). There is a stratum of well-compensated technical employees and managers, including 10s of thousands of "single-digit millionaires". This income and range of assets will support a middle-class lifestyle in Silicon Valley.


Diversity


Gender

In November 2006, the University of California, Davis released a report analyzing business leadership by women within the state. The report showed that although 103 of the 400 largest public companies headquartered in California were located in Santa Clara County (the most of all counties), only 8.8% of Silicon Valley companies had women CEOs. This was the lowest percentage in the state. (San Francisco County had 19.2% and Marin County had 18.5%.) Silicon Valley tech leadership positions are occupied almost exclusively by men. This is also represented in the number of new companies founded by women as well as the number of women-lead startups that receive venture capital funding. Wadhwa said he believes that a contributing factor is a lack of parental encouragement to study science and engineering. He also cited a lack of women role models and noted that most famous tech leaders—like Bill Gates, Steve Jobs, and Mark Zuckerberg—are men. As of October 2014, some high-profile Silicon Valley firms were working actively to prepare and recruit women. ''

Two other cases have been filed against Facebook and Twitter.

reported that 15% of its tech workforce was female, and 3% was Hispanic and 1% was black. In August, Apple reported that 80% of its global tech staff was male and that, in the U.S., 54% of its tech jobs were staffed by Caucasians and 23% by Asians. Soon after, '' USA Today'' published an article about Silicon Valley's lack of tech-industry diversity, pointing out that it is largely white or Asian, and male. "Blacks and Hispanics are largely absent," it reported, "and women are underrepresented in Silicon Valley—from giant companies to start-ups to venture capital firms." Civil rights activist Jesse Jackson said of improving diversity in the tech industry, "This is the next step in the civil rights movement" while T. J. Rodgers has argued against Jackson's assertions.


Municipalities

The following Santa Clara County cities are traditionally considered to be in Silicon Valley (in alphabetical order): The geographical boundaries of Silicon Valley have changed over the years. Historically, the term Silicon Valley was treated as synonymous with Santa Clara Valley, and then its meaning later evolved to refer to Santa Clara County plus adjacent regions in southern San Mateo County and southern Alameda County. However, over the years this geographical area has been expanded to include San Francisco County, Contra Costa County, and the northern parts of Alameda County and San Mateo County, this shift has occurred due to the expansion in the local economy and the development of new technologies.
