Jeffrey Moore's The Gorilla Game and Clayton Christiansen's The Innovator's Dilemma are the most influential intellectual forces in Silicon Valley today.
Christensen is the Robert Jane Cizik professor of business administration at the Harvard Business School and author or co-author of five books including The New York Times best sellers The Innovator's Dilemma and The Innovator's Solution.
Christensen's 1997 book, The Innovator's Dilemma: When New Technologies Cause Great Firms to Fail, describes how new, low-quality products can threaten established ones--such as Nintendo toy cameras threatening mighty Kodak.
