If old America was made in New York or Detroit, modern America is made in Silicon Valley. But what is “Silicon Valley”, where is it? And why is where it is?

It is not made of silicon, and it is not a river valley; but forgetting that, Silicon Valley is probably the most famous valley in the world. Although it is not the place where the first computer was built (which was Manchester, England), Silicon Valley, near San Francisco, was the birthplace of the modern computer industry.

For this, we can say thank you to scientists at the universities in California, and to the Hippies of the 1960s. It was in the nineteen-sixties that American “youth culture” really began. California, of course, already existed; but the Sixties Generation rediscovered it. At the time there were really two different forms of youth culture; the “Beach Boy” culture on the one hand, and the anti-establishment hippies and radical students on the other hand; and they all dreamed of California.

For the Beach Boys, that meant southern California, where they could sing about surfing and cars; for the Hippies and radicals, it meant San Francisco, “flower power” and revolutionary new ideas. The campuses at Berkeley and Stamford, near San Francisco, were hotbeds of new ideas, new technology, new culture, and new ways of living.

When they finished university, many of the best students did not look for jobs with big companies like Ford or Exxon. Instead, they wanted to be free and run their own operations.… and stay in California, not far from San Francisco. Silicon Valley is thus a group of small towns, including Palo Alto and San José, a few miles south of San Francisco.

The high-technology industry was already present around San Francisco. Intel had been founded in 1968, and in the same year, the first computer mouse was built at Stamford University. In 1970, Xerox opened a research center in Palo Alto. There were also other electronics companies, like Hewlett Packard, and Fairchild, the world’s first “semiconductor” company.

Then, in 1976, an electronics student called Steve Jobs started a small computer company in his garage; he gave it the same name as the Beatles’ record company: Apple. Very soon, more companies, like Seagate and Google appeared. “Silicon Valley” had arrived. There was even a sort of primitive Internet connecting many addresses in Silicon Valley, called the Arpanet.

Today, Silicon Valley is still the home of the computer industry; it is still full of high technology, but it is not the only center for high-tech in the USA. Today there are computer firms all over the USA.… and all over the world; but Silicon Valley still has the largest concentration of high-tech companies and research centers.

Microsoft, the world’s biggest high-tech company, is not based in Silicon Valley. It is further north, near Seattle in the state of Washington
