The Valley in general
Silicon Valley
The Silicon Valley lies in the South Bay and the southern Peninsula of the San Francisco Bay Area. Once best known for its prune orchards, the area underwent explosive growth with the creation of the high-tech industry in the 1960s.
"Silicon Valley", first used by Don C. Hoefler, publisher of Microelectronics News, in his article titled "Silicon Valley USA" on January 11, 1971, has become synonymous with the center of high technology research and development. "Silicon" refers to the high concentration of semiconductor and computer-related industries in the area at the time. "Valley" refers to the Santa Clara Valley.
Despite the development of other high-tech economic centers throughout the United States and the world, Silicon Valley continues to be the leading hub for high-tech innovation and development, accounting for 1/3 of all of the venture capital investment in the United States.
Silicon Valley today has extended beyond the greater Santa Clara Valley which includes the entire Santa Clara county and parts of San Mateo, Alameda, and Santa Cruz counties in northern California. It is the southern portion of the San Francisco Bay Area, also known as South Bay, which covers cities such as San Jose, Santa Clara, Sunnyvale, Cupertino and Los Gatos. Silicon Valley also includes parts of the San Francisco Peninsula from Redwood City down to the South Bay, and cities such as Fremont and Newark in the lower East Bay.
