Experimental television broadcasts were started in 1932 using an electromechanical 30 line system developed by John Logie Baird. Limited regular broadcasts using this system began in 1934, and an expanded service (now named the BBC Television Service) started in 1936, alternating between an improved Baird mechanical 240 line system and the all electronic 405 line Marconi-EMI system. The superiority of the electronic system saw the mechanical system dropped early the following year.
