When did color television arrive?

Answer 1

1928 and it was patented, demonstrated and improved by it's inventor John Logie-Baird. John Logie Baird was also the inventor of television as a whole, using mechanical scanning in 1923, and in 1927 he found a way of recording and playing back recorded images on a 78rpm shellac record.

Baird's colour system, which was 3D, used rotating discs with colour filters which were projected onto a cathode-ray tube. It was received with a neon lamp, which was also used in his original 1929 mechanical tests using 30 line and low-defenitition. His system composed of not 30, but 240-600 and 600-1200 lines and showed true colour.

He later, in the 1930's went on to devise a fully electronic cathode-ray tube 3D colour system, named the TeleChrome, which also used 1200 lines as high-standard.

Sadly, in 1946, John Logie-Baird died one week after the Victory Parade, which was not televised in colour, but in black, white and grey. John Logie-Baird died at the age of 57 in his home in Bexhill-On-Sea after a stroke in March that year. The TeleChrome was never used again.

In 1936, most of his TeleChromes were destroyed in a fire at his headquarters in Crystal Palace. This was on 30th November 1936, just 28 days after his 240 line, orange and black neon lamp mechanical transmissions from Alexandra Palace.

Baird's mechanical system was dropped in February 1937, even though the cathode-ray tubes used by his rivals were less popular, as they were developed in 1932.

This meant 270 TV sets became obsolete.
