27 June 1929: the first public demonstration of color TV was held by H. E. Ives and his colleagues at Bell Telephone Laboratories in New York.
The first images were a bouquet of roses and an American flag. A mechanical system was used to transmit 50-line color television images between New York and Washington.
It wasn’t a release of a commercially available product because there wasn’t anything being broadcast at that point in time. It would be another 20-30 years before people started purchasing televisions for their homes en masse.
This was simply the unveiling of the technology as a discovery and it was a really big deal.
It was a pipe dream for most people as even by nearly a decade later (1939) there were only 200 or so televisions in use in the ENTIRE WORLD.
