<P> John Logie Baird set up the Baird Television Development Company in 1926; on 30 September 1929 he made the first experimental television broadcast for the BBC from its studio in Long Acre in the Covent Garden area of London via the BBC's London transmitter . Baird used his electromechanical system with a vertically - scanned image of 30 lines, which is just enough resolution for a close - up of one person, and a bandwidth low enough to use existing radio transmitters . The simultaneous transmission of sound and pictures was achieved on 30 March 1930, by using the BBC's new twin transmitter at Brookmans Park . By late 1930, thirty minutes of morning programmes were broadcast from Monday to Friday, and thirty minutes at midnight on Tuesdays and Fridays after BBC radio went off the air . Baird's broadcasts via the BBC continued until June 1932 . </P> <P> The BBC began its own regular television programming from the basement of Broadcasting House, London, on 22 August 1932 . The studio moved to larger quarters in 16 Portland Place, London, in February 1934, and continued broadcasting the 30 - line images, carried by telephone line to the medium wave transmitter at Brookmans Park, until 11 September 1935, by which time advances in all - electronic television systems made the electromechanical broadcasts obsolete . </P> <P> After a series of test transmissions and special broadcasts that began in August 1936, the BBC Television Service officially launched on 2 November 1936 from a converted wing of Alexandra Palace in London . "Ally Pally" housed two studios, various scenery stores, make - up areas, dressing rooms, offices, and the transmitter itself, which then broadcast on the VHF band . BBC television initially used two systems on alternate weeks: the 240 - line Baird intermediate film system and the 405 - line Marconi - EMI system . The use of both formats made the BBC's service the world's first regular high - definition television service; it broadcast from Monday to Saturday between 15: 00 and 16: 00, and 21: 00 and 22: 00 . The first programme broadcast--and thus the first ever, on a dedicated TV channel--was "Opening of the BBC Television Service" at 15: 00 . The first major outside broadcast was the coronation of King George VI and Queen Elizabeth in May 1937 . </P> <P> The two systems were to run on a trial basis for six months; early television sets supported both resolutions . However, the Baird system, which used a mechanical camera for filmed programming and Farnsworth image dissector cameras for live programming, proved too cumbersome and visually inferior, and ended with closedown (at 22: 00) on Saturday 13 February 1937 . </P>
