In History
  • FIRST DVD

    German, Paul Nipkow developed a rotating-disc technology to transmit pictures over wire in 1884 called the Nipkow disk
  • ELECTRIC TELEVISION

    Electronic television is based on the development of the cathode ray tube, which is the picture tube found in modern TV sets. German scientist, Karl Braun invented the cathode ray tube oscilloscope (CRT) in 1897.
  • fist television

    they attempted to build an electronic television system using a cathode ray tube developed independently in 1907 by English inventor A.A. Campbell-Swinton and Russian scientist Boris Rosing.
  • TV PATENED

    In the 1920's, John Logie Baird patented the idea of using arrays of transparent rods to transmit images for television. Baird's 30 line images were the first demonstrations of television by reflected light rather than back-lit silhouettes
  • FIRST MACHANICAL TELVISION

    Charles Jenkins invented a mechanical television system called radiovision and claimed to have transmitted the earliest moving silhouette images on June 14, 1923
  • FIRST TELEVISION DEMONSTATION

    John Logie Baird showed a working television system to the public in 1925.
  • FIRST TELEVISION BROADCAST

    world's first regular television broadcasts in January 1929
  • IMPROVED RAYTUBE

    Russian inventor, Vladimir Zworykin invented an improved cathode-ray tube called the kinescope in 1929. The kinescope tube was sorely needed for television. Zworykin was one of the first to demonstrate a television system with all the features of modern picture tubes
  • COLORED TV

    Cable television, formerly known as Community Antenna Television or CATV, was born in the mountains of Pennsylvania in the late 1940's. The first successful color television system began commercial broadcasting on December 17, 1953 based on a system designed by RCA.
  • COLORED TV

    Color TV was by no means a new idea, a German patent in 1904 contained the earliest proposal, while in 1925 Zworykin filed a patent disclosure for an all-electronic color television system. A successful color television system began commercial broadcasting, first authorized by the FCC on December 17, 1953 based on a system invented by RCA.
