The valley contains the densest concentration of innovative industry that exists anywhere in the world, including companies that are leaders in such fast-expanding field as computers, semiconductors, lasers, fiber optics, robotics, medical instrumentation, magnetic recording, and educational and consumer electronics. Now, most of the industry is house build. Silicon Valley radiates outward from Stanford University. The San Francisco Bay on the east and the Santa Cruz Mountains on the west and Coast Range contain it to the southeast. At the turn of the century the area was known as the valley of Heart's Delight, when fruit orchards predominated.
Today made of silicon and semiconductor chips is the principal product of the high-tech industries.
And his best graduates had to go to the East Coast to find employment. He designed and built an audio oscillator and a device that generated the signals of varying frequencies. His solution was to establish the then-new radio technology locally. First, he bought together two of the students, William Hewlett and David Packard , founders of the Hewlett-Packard Company, to heed his admonition. Their audio-oscillator, designed with Terman's help, became the basis for a later deal with Walt Disney Studios in 1939, for the film 'Fantasia'.
