This camera uses an 'Emitron' camera tube, developed by the newly incorporated EMI (Electrical & Music Industries) for the BBC (British Broadcasting Corporation) in 1935. It was the first electronic television camera and was used in the newly constructed London Television Station at Alexandra Palace in 1936. A television camera scans the picture from its lens, turning it into a stream of information that can be sent down a cable. To get realistic detail and movement, this has to be done quickly. In the 1930s, when television was being developed, only a beam of electrons could move fast enough. Shown partially sectioned.
