Just south of San Francisco lies a region that has spawned not just new products but whole new industries, from vacuum tubes to radio, microchips to personal computers, mobile devices, apps and social media. Home to Apple and Facebook, Intel and Google, there is simply no other place on earth that can rival its remarkable record of innovation. A new Science Channel three-part documentary series will provide a comprehensive look at the century-and-a-half history of this fascinating place, and reveal how and why it became such a fertile ground for technological breakthroughs. SILICON VALLEY: THE UNTOLD STORY premieres Monday, March 19 at 8, 9 and 10 p.m. It is produced with support from the Alfred P. Sloan Foundation. The Computer History Museum in Mountain View, CA is serving as the community and education outreach partner on the series.
