In this age of an open Internet, it is easy to forget that every American information industry, beginning with the telephone, has eventually been taken captive by some ruthless monopoly or cartel. With all our media now traveling a single network, an unprecedented potential is building for centralized control over what Americans see and hear. Could history repeat itself with the next industrial consolidation? Could the Internetâthe entire flow of American informationâcome to be ruled by one corporate leviathan in possession of “the master switch”? That is the big question of Tim Wu’s pathbreaking book.As Wu’s sweeping history shows, each of the new media of the twentieth centuryâradio, telephone, television, and filmâwas born free and open. Each invited unrestricted use and enterprising experiment until some would-be mogul battled his way to total domination. Here are stories of an uncommon will to power, the power over information: Adolph Zukor, who took a technology once used as commonly as YouTube is today and made it the exclusive prerogative of a kingdom called Hollywood . . . NBC’s founder, David Sarnoff, who, to save his broadcast empire from disruptive visionaries, bullied one inventor (of electronic television) into alcoholic despair and another (this one of FM radio, and his boyhood friend) into suicide . . . And foremost, Theodore Vail, founder of the Bell System, the greatest information empire of all time, and a capitalist whose faith in Soviet-style central planning set the course of every information industry thereafter.Explaining how invention begets industry and industry begets empireâa progress often blessed by government, typically with stifling consequences for free expression and technical innovation alikeâWu identifies a time-honored pattern in the maneuvers of today’s great information powers: Apple, Google, and an eerily resurgent AT&T. A battle royal looms for the Internet’s future, and with almost every aspect of our lives now dependent on that network, this is one war we dare not tune out.Part industrial exposé, part meditation on what freedom requires in the information age, The Master Switch is a stirring illumination of a drama that has played out over decades in the shadows of our national life and now culminates with terrifying implications for our future.

What if digital communication felt as real as being touched? This question led Michael Chorost to explore profound new ideas triggered by lab research around the world, and the result is the book you now hold. Marvelous and momentous, World Wide Mind takes mind-to-mind communication out of the realm of science fiction and reveals how we are on the verge of a radical new understanding of human interaction. Chorost himself has computers in his head that enable him to hear: two cochlear implants. Drawing on that experience, he proposes that our Paleolithic bodies and our Pentium chips could be physically merged, and he explores the technologies that could do it. He visits engineers building wearable computers that allow people to be online every waking moment, and scientists working on implanted chips that would let paralysis victims communicate. Entirely new neural interfaces are being developed that let computers read and alter neural activity in unprecedented detail. But we all know how addictive the Internet is. Chorost explains the addiction: he details the biochemistry of what makes you hunger to touch your iPhone and check your email. He proposes how we could design a mind-to-mind technology that would let us reconnect with our bodies and enhance our relationships. With such technologies, we could achieve a collective consciousness - a World Wide Mind. And it would be humankind's next evolutionary step. With daring and sensitivity, Chorost writes about how he learned how to enhance his relationships by attending workshops teaching the power of touch. He learned how to bring technology and communication together to find true love, and his story shows how we can master technology to make ourselves more human rather than less. World Wide Mind offers a new understanding of how we communicate, what we need to connect fully with one another, and how our addiction to email and texting can be countered with technologies that put us - literally - in each other's minds.
