The 1890s advertising card shown above depicts a representation of the possible future of “home theater.”Īmerican inventor Charles Francis Jenkins transmitted pictures of Herbert Hoover, then Secretary of Commerce, from Washington to Philadelphia by radio in 1923, and he demonstrated a mechanical television scanning system using a revolving disk in 1925. Scientists from around the world worked to perfect television for decades, with the key breakthroughs coming in the early 20th century, the invention springing from the work of many minds.

Wells began postulating the idea of “seeing at a distance” – as the earliest concepts of television were predicted in the 18th and 19th centuries. Writers such as Walter Scott, Jules Verne, Mark Twain, and H.G. Telegraph usage faded as radio became easy to use and popularized as radio was being developed, the telephone quickly became the fastest way to communicate person-to-person after television was perfected and content for it was well developed, it became the dominant form of mass-communication technology the internet came next, and newspapers, radio, telephones, and television are being rolled into this far-reaching information medium. Printing remained the key format for mass messages for years afterward, but the telegraph allowed instant communication over vast distances for the first time in human history.

This timeline is provided to help show how the dominant form of communication changes as rapidly as innovators develop new technologies.Ī brief historical overview: The printing press was the big innovation in communications until the telegraph was developed.
