A sign describing the "Birthplace of Silicon Valley" garage, 2016
Silicon Valley
is a
nickname for the southern portion of the San Francisco Bay Area, in the
northern part of the U.S. state of California. The "valley" in its
name refers to the Santa Clara Valley in Santa Clara County, which includes the
city of San Jose and surrounding cities and towns, where the region has been
traditionally centered. The region has expanded to include the southern half of
the San Francisco Peninsula in San Mateo County, and southern portions of the
East Bay in Alameda County.
The word
"silicon" originally referred to the large number of silicon chip
innovators and manufacturers in the region, but the area is now the home to
many of the world's largest high-tech corporations, including the headquarters
of 39 businesses in the Fortune 1000, and thousands of startup companies.
Silicon Valley also accounts for one-third of all of the venture capital
investment in the United States, which has helped it to become a leading hub
and startup ecosystem for high-tech innovation and scientific development. It
was in the Valley that the silicon-based integrated circuit, the
microprocessor, and the microcomputer, among other key technologies, were
developed. As of 2013, the region employed about a quarter of a million
information technology workers.
As more
high-tech companies were established across the Santa Clara Valley, and then
north towards the Bay Area's two other major cities, San Francisco and Oakland,
the "Silicon Valley" has come to have two definitions: a geographic
one, referring to Santa Clara County, and a metonymical one, referring to all
high-tech businesses in the Bay Area or even in the United States. The term is
now generally used as a synecdoche for the American high-technology economic
sector. The name also became a global synonym for leading high-tech research
and enterprises, and thus inspired similar named locations, as well as research
parks and technology centers with a comparable structure all around the world.
