orcle - noun
(Lifestyle and Leisure) (Science and Technology) In the UK, the trade mark of a teletext system (see tele- ) originally operated by the IBA. Etymology: A figurative use of oracle, based on the popular transferred sense of the phrase consult the oracle, 'to seek information from an authority': the purpose of the service is to provide information on the television screen. History and Usage: Oracle was introduced in the mid seventies and is now a standard option on most new television sets in the UK . The name has been used in other trade marks, especially in information technology. Ceefax and Oracle are both teletext systems. At present teletext is limited to the amount of information that may be transmitted on the two available lines on a television screen, but it is a free service. Bookseller 29 Mar. 1980, p. 1430
