Silicon Valley corresponds roughly to the geographical region of the Santa Clara Valley in Northern California and has become a synonym for entrepreneurial high-tech and the subsequent start-up ventures that have propelled the United States’ economy for decades. One city in the valley alone, San José, has the third highest GDP for a city in the world.
Silicon refers to a key ingredient in microprocessor production that made computers available to consumers. But innovation has been at home in the valley for much longer. The first ship-to-shore telegraph was sent to San Francisco in 1899, early inventors have gathered here for inspiration and United States military scientists and researchers have bases there to stay in close symbiosis with new ideas in the public sector.
