This anthology assembles primary documents chronicling the development of the phonograph, talking pictures, and the radio. These three sound technologies shaped Americans' relation to music from the late nineteenth century until the end of the Second World War, by which time they were thoroughly integrated into Americans' everyday lives. There are more than 120 selections between the collection's first piece, an article on the phonograph written by Thomas Edison in 1878, and its last, a column published in 1945, advising listeners "desirous of gaining more from music as presented by the radio." Among the selections are articles from popular and trade publications, advertisements, fan letters, corporate records, fiction, and sheet music. Taken together, the selections capture how the new sound technologies were shaped by developments such as urbanization, the increasing value placed on leisure time, and the rise of the advertising industry.
