  1. For example, the United States, Great Britain, Germany, and the former Soviet Union all had operational television stations and a limited number of viewers by 1939. Very few cities in each country had television service. Television broadcasts were not yet available in most places.

  2. RCA introduced television to the American public at the 1939 World's Fair. Before the fair, they published a brochure for their dealers to explain television. The opening ceremony and events at the fair were televised, and NBC began regularly scheduled broadcasts.

  3. Apr 30, 2014 · The 1939 World’s Fair in New York City opened 75 years ago today on Sunday, April 30th, 1939. With it came the official start of the first regularly scheduled television service in the United States aimed at the public, over RCA’s experimental station W2XBS.

    Joseph Henry's and Michael Faraday's work with electromagnetismjumpstarts the era of electronic communication.

    Abbe Giovanna Caselli invents his Pantelegraph and becomes the first person to transmit a still image over wires.

    Scientist Willoughby Smith experiments with selenium and light, revealing the possibility for inventors to transform images into electronic signals.

    Boston civil servant George Carey was thinking about complete television systems and in 1877 he put forward drawings for what he called a selenium camera that would allow people to see by electricity. Eugen Goldstein coins the term "cathode rays" to describe the light emitted when an electric current was forced through a vacuum tube.

    Scientists and engineers like Valeria Correa Vaz de Paiva, Louis Figuier, and Constantin Senlecq were suggesting alternative designs for telectroscopes.

    Inventors Alexander Graham Bell and Thomas Edisontheorize about telephone devices that transmit images as well as sound. Bell's photophoneused light to transmit sound and he wanted to advance his device for image sending. George Carey builds a rudimentary system with light-sensitive cells.

    Paul Nipkowsends images over wires using a rotating metal disk technology calling it the electric telescope with 18 lines of resolution.

    At the World's Fair in Paris, the first International Congress of Electricity was held. That is where Russian Constantin Perskyi made the first known use of the word "television." Soon after 1900, the momentum shifted from ideas and discussions to the physical development of television systems. Two major paths in the development of a television sys...

    Lee de Forest invents the Audion vacuum tube that proves essential to electronics. The Audion was the first tube with the ability to amplify signals. Boris Rosing combines Nipkow's disk and a cathode ray tube and builds the first working mechanical TV system.

    Campbell Swinton and Boris Rosing suggest using cathode ray tubes to transmit images. Independent of each other, they both develop electronic scanning methods of reproducing images.

  4. For example, the United States, Great Britain, Germany, and the former Soviet Union all had operational television stations and a limited number of viewers by the year 1939. However, in those countries, only very few cities in each country had television service.
