An information service in which pages of text are transmitted to the home or office for display on a television set. The information is given under various headings, with a menu call-up system, and includes latest stock exchange prices. The two systems originally developed in the UK were Ceefax, provided by the BBC, and Oracle, provided by ITV. Oracle was replaced by a new system provided by Teletext Ltd in 1993 and Ceefax was phased out in favour of a digital text service from 2001. See also viewdata.
