Geek Fact for June 27th

In 1929, the first mechanically scanned color television was demonstrated by Bell Laboratories in New York City.

It consisted of three complete systems of photoelectric cells, amplifiers, glow-tubes, and color filters, with a series of mirrors to superimpose the red, green, and blue images into one full color image.

  1. Are we talking “worlds first” American color tv. Or worlds first ever color tv.
    Found this on Wikipedia;

    John Logie Baird demonstrated the world’s first color transmission on July 3, 1928, using scanning discs at the transmitting and receiving ends with three spirals of apertures, each spiral with filters of a different primary color; and three light sources at the receiving end, with a commutator to alternate their illumination.[7] Baird also made the world’s first color broadcast on February 4, 1938, sending a mechanically scanned 120-line image from Baird’s Crystal Palace studios to a projection screen at London’s Dominion Theatre.

    Looks like us Brits got there first!!

  2. Hmmm. Pretty interesting stuff. I was going to say Bell had the first mechanically scanned color TV. I’m not sure that that is different than what you describe though. Maybe you Brits did get there first!
