This RCA-produced film tells the short history of television from the perspective held in 1956, which was itself an early point in the TV’s history. After a detailed explanation of how TVs work and what the components look like, the film goes on to talk about how TV design is now moving toward reducing the size and cost of components and improving picture quality. We get to see many “TV firsts,” including footage of the first president on TV, President Roosevelt opening the NY World’s Fair, the King and Queen of England’s visit, and the 1940 Republican Convention in Philadelphia. David Sarnoff narrates the film and appears as an interviewer, asking Vladimir Zworykin about TV technology at RCA. The last third of the film is in color, and it talks about how color television works, then goes to a listing of NBC broadcast shows, including “Ding Dong School.” Given that this is such a collection of precious early television, this film is tough to top when it comes to exploring television history.
