Available in PDF, EPUB and Kindle. Book excerpt: “A rollicking history of the telephone system and the hackers who exploited its flaws.” —Kirkus Reviews, starred review Before smartphones, back even before the Internet and personal computers, a misfit group of technophiles, blind teenagers, hippies, and outlaws figured out how to hack the world’s largest machine: the telephone system. Starting with Alexander Graham Bell’s revolutionary “harmonic telegraph,” by the middle of the twentieth century the phone system had grown into something extraordinary, a web of cutting-edge switching machines and human operators that linked together millions of people like never before. But the network had a billion-dollar flaw, and once people discovered it, things would never be the same. Exploding the Phone tells this story in full for the first time. It traces the birth of long-distance communication and the telephone, the rise of AT&T’s monopoly, the creation of the sophisticated machines that made it all work, and the discovery of Ma Bell’s Achilles’ heel. Phil Lapsley expertly weaves together the clandestine underground of “phone phreaks” who turned the network into their electronic playground, the mobsters who exploited its flaws to avoid the feds, the explosion of telephone hacking in the counterculture, and the war between the phreaks, the phone company, and the FBI. The product of extensive original research, Exploding the Phone is a groundbreaking, captivating book that “does for the phone phreaks what Steven Levy’s Hackers did for computer pioneers” (Boing Boing). “An authoritative, jaunty and enjoyable account of their sometimes comical, sometimes impressive and sometimes disquieting misdeeds.” —The Wall Street Journal “Brilliantly researched.” —The Atlantic “A fantastically fun romp through the world of early phone hackers, who sought free long distance, and in the end helped launch the computer era.” —The Seattle Times

Based on research conducted in dozens of countries, this insightful and entertaining book examines the once unexpected interaction between humans and cell phones, and between humans, period. The compelling discussion and projections about the future of the telephone should give designers everywhere a more informed practice and process, and provide researchers with new ideas to last years.*Rich Ling (an American working in Norway) is a prominent researcher, interviewed in the new technology article in the November 9 issue of the New York Times Magazine. *A particularly "good read", this book will be important to the designers, information designers, social psychologists, and others who will have an impact on the development of the new third generation of mobile telephones. *Carefully and wittily written by a senior research scientist at Telenor, Norway's largest telecommunications company, and developer of the first mobile telephone system that allowed for international roaming.
