Colour TV in the USA

1929 | June 27 – Herbert E. Ives and his colleagues at Bell Laboratories in  NewYork produced and demonstrated colour TV mechanically. The first images were of a bouquet of roses and an American flag. The system used a single spiral, through the holes of which light from three coloured sources was passed. A mechanical system was used to transmit 50-line colour television images from New York, New York to Washington DC.
