San Jose is the cultural, financial, and political center of Silicon Valley. Founded in 1777, San Jose was California's first civilian settlement, its first incorporated city after Sacramento, and site of the first capital. In 1909, Charles D. Herrold established the world's first radio broadcasting station in the Garden City Bank Building at the southwest corner of First and San Fernando. Located in the Santa Clara Valley along the Coyote and Guadalupe rivers, 42 miles southeast of San Francisco, San Jose averages more than 300 sunny days per year. Elevation points within the city limits rise from sea level to 4,372 feet. San Jose is the headquarters of Adobe, Cisco Systems, eBay, PayPal, Hewlett Packard, and Zoom.
