Teletext systems systems existed, but by the end of the decade they converged, with the creation of the World System Teletext (WST). WST remained in use for analogue broadcasts until 2012. The first test transmissions were made by the BBC in 1972–74, with the name "Ceefax" ("see facts"). The Ceefax system went live on 23 September 1974 with thirty pages of information. Due to the adoption of a common teletext standard (WST), the Ceefax system ceased in 1976. The name was retained for the service itself, that continued after that year using the WST standard. "ORACLE" was first broadcast on the ITV
Teletext during which the webpages of major news sites became inaccessible because of the high demand. Teletext is also used for carrying special packets interpreted by TVs and video recorders, containing information about subjects such as channels and programming. Although the term "teletext" tends to be used to refer to the PAL-based system, or variants, the recent availability of digital television has led to more advanced systems being provided that perform the same task, such as MHEG-5 in the UK, and Multimedia Home Platform. Teletext is a means of sending text and simple geometric shapes to a properly equipped television screen
