Ceefax was launched in the UK by the BBC on 28 September 1974. It was developed by BBC engineers who were working on a way to provide subtitles for deaf people. They were able to use the 'spare lines' on top of an analog television signal to incorporate words and simple pictures. The Ceefax service is still available to analog television viewers.
