ANSWERING MACHINES. The idea of devices to record telephone calls occurred simultaneously to several inventors, among them Thomas Edison, in the late nineteenth century. Edison's unsuccessful attempts to record a telephone call mechanically led to the invention of the phonograph, which achieved commercial success for entertainment purposes. In 1890, Valdemar Poulsen invented a telegraphone, the first magnetic recorder. Operating much like a modern tape recorder, the telegraphone was an automatic telephone answering machine, but it had no outgoing message. Following the advent of electronic tubes in the 1920s, several individuals and firms offered fully automatic answering machines that used magnetic tape and operated along the lines of the later, more familiar machines. These were used widely in Europe but were banned in the United States by AT&T, which saw them as a threat.
After World War II, new regulations made it possible to offer for sale answering machines such as one called the Electronic Secretary. Responding to demands from businesses, Bell Operating Companies began leasing answering machines in 1950. Reductions in cost stimulated demand for these machines by the mid-1970s, and they gained recognition as they were featured in motion pictures and television shows. With the dissolution of AT&T in 1984, most local operating companies ceased enforcing the remaining restrictions on answering machine use. Sales rose dramatically, exceeding one million units per year in the early 1980s. By the mid-1990s a majority of households owned a machine.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
