Baird's Transmissions from the Crystal Palace
In 1933 Baird built studios and a transmitter at the Crystal Palace, which broadcast pictures with up to 180 lines, using the intermediate film technique, where programs were produced on 16 mm film, developed quickly, and then televised using a flying spot scanner. Broadcasting continued until a fire destroyed the Crystal Palace in 1936. Here is the story, from a 1993 article in 405 Alive, and a 1935 article in Radio World.
