A complete history of how the telegraph revolutionized technological practice and life in America. Telegraphy in the nineteenth century approximated the internet in our own day. Historian and electrical engineer David Hochfelder offers readers a comprehensive history of this groundbreaking technology, which employs breaks in an electrical current to send code along miles of wire. The Telegraph in America, 1832–1920 examines the correlation between technological innovation and social change and shows how this transformative relationship helps us to understand and perhaps define modernity. The telegraph revolutionized the spread of information—speeding personal messages, news of public events, and details of stock fluctuations. During the Civil War, telegraphed intelligence and high-level directives gave the Union war effort a critical advantage. Afterward, the telegraph helped build and break fortunes and, along with the railroad, altered the way Americans thought about time and space. With this book, Hochfelder supplies us with an introduction to the early stirrings of the information age.

This unique history of telegraphic news gathering and news flow evaluates the effect of the innovative technology on the evolution of the concept of news and journalistic practices. It also addresses problems of technological innovation and diffusion. Menahem Blondheim's main concern, however, is the development of oligopoly in business and the control revolution in American society. He traces the discovery of timely news as a commodity, presenting a lively and detailed account of the emergence of the New York Associated Press (AP) as the first private sector national monopoly in the United States and Western Union as the first industrial one.
