How did one of the great inventions of the nineteenth century -- Thomas Edison's phonograph -- eventually lead to one of the most culturally and economically significant technologies of the twentieth and twenty-first centuries? Sound Recording traces the history of the business boom and the cultural revolution that Edison's invention made possible.

Recorded sound has pervaded nearly every facet of modern life -- not just popular music, but also mundane office dictation machines, radio and television programs, and even telephone answering machines. Just as styles of music have evolved, so too have the formats through which sound has been captured -- from 78s to LPs, LPs to cassette tapes, tapes to CDs, and on to electronic formats. The quest for better sound has certainly driven technological change, but according to David L. Morton, so have business strategies, patent battles, and a host of other factors.

"Electronics" provides a welcome, comprehensive history of one of the late twentieth century's greatest technologies: electronic devices. Some of them, the laser and the microchip for example, have become household words. Yet their origins and operation are largely unknown to the general public, remaining mysterious outside the field of engineering. Their advent brought about many of the most important historical developments in recent memory--the rise of television, the Cold War, the Space Race, the growth of Asian semiconductor manufacturers, and the emergence of the surveillance society.

"Electronics" also relates the fascinating stories of how scientists and engineers created and commercialized such devices as the transistor, the Magnetron tube used to power microwave ovens, the CRT (cathode ray tube), the laser, the first integrated circuit, the microprocessor, and memory chips.

David L. Morton examines the process of invention, innovation, and diffusion of communications technology, using the history of sound recording as the focus. Off the Record demonstrates how the history of both the hardware and the ways people used it is essential for understanding why any particular technology became a fixture in everyday life or faded into obscurity. Morton's approach to the topic differs from most previous works, which have examined the technology's social impact, but not the reasons for its existence. Recording culture in America emerged, Morton writes, not through the dictates of the technology itself but in complex ways that were contingent upon the actions of users.Each of the case studies in the book emphasizes one of five aspects of the culture of recording and its relationship to new technology, at the same time telling the story of sound recording history. One of the misconceptions that Morton hopes to dispel is that the only important category of sound recording involves music. Unique in his broad-based approach to sound technology, the five case studies that Morton investigates are : The phonograph record Recording in the radio business The dictation machine The telephone answering machine, and Home taping Readers will learn, for example, that the equipment to create the telephone answering machine has been around for a century, but that the ownership and use of answering machines was a hotly contested issue in the telephone industry at the turn of the century, hence stifling its commercial development for decades. Morton also offers fascinating insight into early radio: that, while The Amos and Andy Show initially was pre-recorded and not broadcast live, the commercial stations saw this easily distributed program as an economic threat: many non-network stations could buy the disks for easy, relatively inexpensive replaying. As a result, Amos and Andy was sold to Mutual and went live shortly afterward.
