Technology consultant and historian Mark Schubin talks about the history of television, including how opera inspired the idea of remote listening and viewing. Next, he traces the development of TV technology, starting in 1843 with Alexander Bain's patent for a mechanical image scanner. Other topics include George Carey's early work on scanning cameras, the Siemens Artificial Eye from 1876, Boris Rosing's picture tube from 1906, Alan Campbell-Swinton's end-to-end system in 1912, and television demonstrations at the 1939 World's Fair. We end up discussing the current state of TV and what we might expect in the future, plus answers to chatroom questions and more.
