passage: Silicon Valley
Silicon Valley is a region in the southern San Francisco Bay Area of Northern California that serves as a global center for high technology, innovation and social media. It corresponds roughly to the geographical area of Santa Clara Valley. San Jose is the Valley's largest city, the third largest in California, and the tenth largest in the United States. Other major Silicon Valley cities include Palo Alto, Menlo Park, Cupertino, Santa Clara, Mountain View, and Sunnyvale.[1] The San Jose Metropolitan Area has the third highest GDP per capita in the world (after Zurich, Switzerland and Oslo, Norway), according to the Brookings Institution.[2]
passage: Silicon Valley
In 1933, Air Base Sunnyvale, California, was commissioned by the United States Government for use as a Naval Air Station (NAS) to house the airship USS Macon in Hangar One. The station was renamed NAS Moffett Field, and between 1933 and 1947, U.S. Navy blimps were based there.[10] A number of technology firms had set up shop in the area around Moffett Field to serve the Navy. When the Navy gave up its airship ambitions and moved most of its west coast operations to San Diego, the National Advisory Committee for Aeronautics (NACA, forerunner of NASA) took over portions of Moffett Field for aeronautics research. Many of the original companies stayed, while new ones moved in. The immediate area was soon filled with aerospace firms, such as Lockheed.
