Telidon

Telidon (from the Greek words τῆλε, tele "at a distance" and ἰδών, idon "seeing") was a videotex/teletext service developed by the Canadian Communications Research Centre (CRC) during the late 1970s and early 1980s. The CRC referred to Telidon as a "second generation" system, offering improved performance, 2D color graphics, multi-lingual support and a number of different interactivity options supported on various hardware. With additional features added by AT&T Corporation, Telidon became the basis for the NAPLPS standard.
