BBC Television 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.[5][6] "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.[7] The first programme broadcast – and thus the first ever, on a dedicated TV channel – was "Opening of the BBC Television Service" at 15:00.[8] The first major outside broadcast was the coronation of King George VI and Queen Elizabeth in May 1937.
