Silicon Valley has been often imitated but never duplicated. This new series encompasses a much broader story - one that is largely untold. It includes interviews with some of the Valley's most prominent innovators - including Apple co-founder Steve Wozniak - who helped make the region what it is today, and the tech entrepreneurs - WhatsApp co-founder Jan Koum among them - who are leading the Valley into the future. Koum, who grew up on food stamps and later sold WhatsApp to Facebook for $19 billion, says that "I could not have built WhatsApp outside of Silicon Valley - no chance." While Silicon Valley prides itself on disrupting old ways of doing things, it has largely failed to dismantle its barriers to women. Women have long been excluded from the valley's top jobs, even though they've been essential to its history. Kim Polese, a leading Silicon Valley entrepreneur and innovator, and currently chairman of CrowdSmart, and Heidi Roizen, a venture capitalist, corporate director and entrepreneur who co-founded the software company T/Maker, both relay stories about the challenges that women have faced in the Valley.
