An industrial name and its geography
The name initially referred to electronics around the Santa Clara Valley and neighbouring peninsula, with silicon identifying the semiconductor material. Usage expanded with industry. It has a geographical basis without being an independent city formally named Silicon Valley.
Universities, firms and research settings
Institutions including Stanford supplied research, people and links with firms; its research park, established in 1951, was one part of this setting. Technical labour, manufacturing and defence and other markets also mattered, rather than the region arising from a university acting alone.
Company formation and movement of people
Shockley Semiconductor, Fairchild and subsequent spin-offs illustrate movement among firms by engineers and entrepreneurs. New companies carried experience but also needed capital, production and customers. Semiconductor, personal-computing and software developments belong to different stages within this evolving region.
A name publicized in 1971
Journalist Don Hoefler’s 1971 reporting popularized the name. Silicon Valley later became a metaphor for startup clusters, but the actual region’s history involves land use, work, cooperation and competition as well as celebrated companies, and resists reduction to one success story.
