This website contains articles and extracts about early radio and related technologies in the United States from 1897-1927. It is organized chronologically and divided into 24 sections. Each section is a long-form essay, containing numerous hyperlinks to reproductions or transcriptions of original primary documents, including documents relating to the efforts to provide entertainment and news over the telephone in the first decades of the 20th century. Essays vary in length, most 1,000 - 2,000 words, and many are original essays by the site's creator. The first section offers an overview of the individuals, activities, and technical advances that characterize the early 20th century.
