The Master Switch: The Rise and Fall of Information Empires (Vintage) [Paperback] for $9.71

From Publishers Weekly Starred Review. According to Columbia professor and policy advocate Wu (Who Controls the Internet), the great information empires of the 20th century have followed a clear and distinctive pattern: after the chaos that follows a major technological innovation, a corporate power intervenes and centralizes control of the new medium--the master switch. Wu chronicles the turning points of the century' s information landscape: those decisive moments when a medium opens or closes, from the development of radio to the Internet revolution, where centralizing control could have devastating consequences.
