First programmable computer. Chris Burton holding a cathode ray tube (CRT) for use in the restoration of the first stored-program computer. Burton heads a team from the Computer Conservation Society which aims to restore "Baby", this computer, which ran the world's first program on 21 June 1948. It was developed at Manchester University, England, by Tom Kilburn and Freddie Williams. Baby is over 2 metres tall, and almost five metres wide, and stored information on a CRT identical to this one. The screen has 32 lines of 32 digits, giving a total memory of 1024 bits (binary digits). Modern computers may have a million times this, or more.
