The media in the San Francisco Bay Area has historically focused on San Francisco but also includes two other major media centers, Oakland and San Jose. The Federal Communications Commission, Nielsen Media Research, and other similar media organizations treat the San Francisco-Oakland-San Jose Area as one entire media market. The region hosts to one of the oldest radio stations in the United States still in existence, KCBS (AM) (740 kHz), founded by engineer Charles Herrold in 1909. As the home of Silicon Valley, the Bay Area is also a technologically advanced and innovative region, with many companies involved with Internet media or influential websites.
