On 26 January 1926, Baird gave the first public demonstration of true television images for members of the Royal Institution and a reporter from The Times in his laboratory at 22 Frith Street in the Soho district of London. Baird initially used a scan rate of 5 pictures per second, improving this to 12.5 pictures per second. It was the first demonstration of a television system that could scan and display live moving images with tonal graduation.
