"The most fascinating aspect of Off the Record involves tracing the complex paths by which devices that are now commonplace originally came into being, gained markets, and slowly evolved. Each chapter is filled with brave hopes, false starts, mistaken social assumptions, and solutions that were almost, but not quite, right. Morton does a fine job of demonstrating multiple contingencies in the by-no-means-certain evolution of now-familiar technologies." --Jeffery L. Meikle, American Studies, University of Texas at Austin David Morton examines the process of invention, innovation, and diffusion of communications technology, using the history of sound recording as the focus. Recording culture in America emerged, Morton writes, not through the dictates of the technology alone but in complex ways that were contingent upon the actions of users. 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 these items was a hotly contested issue in the telephone industry at the turn of the twentieth-century. As a result, its commercial development was stifled for decades. Morton illustrates his broad-based approach to sound technology with five case studies: the phonograph record, recording in the radio business, the dictation machine, the telephone answering machine, and home taping. Each of these case studies dispels the popular notion that recording is all about music, and they tell a much more complete story of sound recording technology and history.
