Silicon Valley is on the south side of San Francisco Bay in northern California. It is a region intertwined with many settlements here. In 1971, this area was first called "Silicon Valley" by Donald Hoefler, a local news bulletin writer, and has been called that name to this day. Today, Silicon Valley, where the headquarters of many technology companies are located, has reached its current world-famous reputation, especially with the technological developments in the last 20-30 years and the beginning of the internet age, although its history goes back to the 1950s.

The biggest factor in the establishment of Silicon Valley in this region is "Stanford University", a world-renowned university located here. In 1951, the University decided to create a research park on its own grounds, where only technology-related companies would have their offices, to meet its financial growth needs and provide local employment opportunities for graduate students.

At first, mostly military-oriented technology companies came to the park, but later companies such as "Hewlett-Packard" started to settle here.

In 1956, William Shockley, who had previously worked on transistors at Bell Laboratories, founded his own company, Shockley Semiconductor Laboratories. One year later, because William Shockley's company failed in terms of business and he had difficulty in getting along with his employees, 8 engineers left the company and set up a new company called "Fairchild Semiconductor". This event has an important role in the development of Silicon Valley.

Their departure inspired those who wanted to establish their own companies, especially in Silicon Valley and in electronics companies in general, instead of continuing their careers, and a business mobility model was formed in this direction. Robert Noyce, Gordon Moore and Andrew Grove, who worked at "Fairchild Semiconductor", were influenced by this trend and left the company to found their own company "Intel". A short time later, W. J. Sanders, who was also working for the same company, left the company to found his own company "Advanced Micro Devices", or "AMD" as it is known by everyone.

Later, those who left the companies they worked in Silicon Valley, started to establish their own companies such as Atari and Apple.

This development of Silicon Valley led to a decrease in the number of military companies and an increase in the number of computer and technology companies. Investors began to put capital into these emerging companies. As investors' investment in such startups has turned California into a center of attraction, the same model has been tried to be applied in other US states. But none of them have been like Silicon Valley. The reason for this was that electronics companies wanted to be side by side with other competitor or complementary companies in their sector. Thus, every national or international company related to the sector either moved their headquarters here or opened a large office here.

This situation has transformed Silicon Valley not only into a region where companies are located, but also a place where various organizations are held that bring together different company employees outside of work, and where there are many investors. Many people's new business ideas came up here or came here to bring it to life. The good ones quickly took investments and implemented them.

The big US technology companies that have emerged in recent years were either founded this way or reached their current size thanks to their relocation here. Examples of these companies are Google, Apple, Facebook, Twitter, Apple, Uber, AirBnB, Netflix, Instagram, Western Digital, WhatsApp, eBay, Nvidia, PayPal, Adobe, Oracle, Cisco, LinkedIn and Udemy.

This popularity of Silicon Valley brings with it some big problems. The most important of these is that life is very expensive. The fact that the region is a center of attraction and the high salaries of the employees have increased the rental prices especially here. Also, the high taxes in the State of California have been a big problem for companies lately.

The development of technology and the pandemic process enabled company personnel to remotely work. That's why it made many companies look forward to the idea of leaving a region like Silicon Valley where both rent prices and taxes are at very high levels. Today, some companies have started to move their headquarters to other technology parks in the USA. The most important of these is the city of Austin in Texas. In addition, technology parks located in cities such as Atlanta, Pittsburgh, Minneapolis, Charlotte, Baltimore offer several advantages for hosting "Information Technology" companies.
