In 2009 BlackBerry controlled half of the smartphone market. Today that number is one percent. What went so wrong? Losing the Signal is a riveting story of a company that toppled global giants before succumbing to the ruthlessly competitive forces of Silicon Valley. This is not a conventional tale of modern business failure by fraud and greed. The rise and fall of BlackBerry reveals the dangerous speed at which innovators race along the information superhighway. With unprecedented access to key players, senior executives, directors, and competitors, Losing the Signal unveils the remarkable rise of a company that started above a bagel shop in Ontario. At the heart of the story is an unlikely partnership between a visionary engineer, Mike Lazaridis, and an abrasive Harvard Business School grad, Jim Balsillie. Together they engineered a pioneering pocket email device that became the tool of choice for presidents and CEOs. The partnership enjoyed only a brief moment on top of the world, however. At the very moment BlackBerry was ranked the world's fastest growing company, internal feuds and chaotic growth crippled the company as it faced its gravest test: Apple and Google's entry into mobile phones.
