John Logie Baird, the Scottish inventor, developed an electromechanical TV system in the 1920's and gave frequent public demonstrations. The publicity encouraged EMI to develop a practical all-electronic system, similar to today's. In 1936 the BBC transmitted both systems, but EMI's was judged superior.
