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 to the TV station. These services have since been superseded by the World Wide Web. With the advent of digital television some countries adopted the name "digital teletext" for newer standards, despite the older teletext standards' digital nature. "Digital teletext" is encoded with standards including MHEG-5 and Multimedia Home Platform (MHP). Other countries use the same teletext streams as before on DVB transmissions, due to the DVB-TXT and DVB-VBI sub-standards.
