  2. The concept of television is the work of many individuals in the late 19th and early 20th centuries. The first practical transmissions of moving images over a radio system used mechanical rotating perforated disks to scan a scene into a time-varying signal that could be reconstructed at a receiver back into an approximation of the original image.

    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.
