spread of film companies across the U.S. Many worked with equipment for which they did not own the patent rights, and thus filming in New York was "dangerous"; it was too close to Edison's company headquarters, and to his agents which the company sent out to seize "illegal" cameras. By 1912, most major film companies had set up movie production facilities in Southern California near or in Los Angeles because of the region's favorable year-round weather and the rapidly growing supply of "talent" both before and behind the cameras. Since the 1920s California continues to be a major U.S. center for motion-picture shows, television shows, cartoons, and related entertainment industries, especially in Hollywood and Burbank areas. Since 1945, manufacturing of electronic equipment, computers, machinery, transportation equipment, and metal products, has increased rapidly while aircraft and naval construction has largely ceased. Stanford University, its affiliates, and graduates played a major role in the development of California's electronics and high-tech industry. From the 1890s, Stanford University's leaders saw its mission as leading the development of the West and shaped the school accordingly. Regionalism helped align Stanford's interests with those of the Stanford area's high-tech firms for the first fifty years of Silicon Valley's development. During the 1940s and 1950s, Frederick Terman, as Stanford's dean of engineering and provost, encouraged faculty and graduates to start their own companies. He is credited with nurturing Hewlett-Packard, Varian Associates, and other high-tech firms such as Apple Inc., Google, etc. in what would become Silicon Valley that grew up around the Stanford campus. Despite the development of other high-tech economic centers throughout the United States and the world, Silicon Valley continues to be a leading hub for high-tech innovation and development, accounting for one-third of all of the venture capital investment in the United States. Geographically, Silicon Valley encompasses all of the Santa Clara Valley, the southern Peninsula, and the southern East Bay. A number of high-tech companies and small low-tech, often low-wage, companies are also located in Southern California. Tourism is also an important part of California's economy. Yosemite National Park was established in 1890, followed by nine other national parks and seashores, as well as various other protected areas across California. Disneyland, established in 1955, and other theme parks draw millions of visitors each year. California also pioneered numerous innovations in retailing during the mid-20th century, particularly fast food restaurants and credit cards. Nationwide fast
