  Canadian Journal of Communication - Vol. 16, No. 2 (1991)   (Site not responding. Last check: 2007-10-29)
For those who are not familiar with the project, Telidon was founded by the DOC in August 1978 and was charged with the task of developing an alpha-numeric (ASCII) videotex protocol, and with the subsequent implementation of a data telecommunication network which would operate with the said protocol (Gillies, 1990; Godfrey & Chang, 1981).
For him, Telidon was an ``entrelacs complexe'' (complex interweave), and failed largely because the bureaucratic and industrial representatives on the scene were unable to muster the proportion of users necessary to command significant commercial investment toward the wholesale erection of national scale systems in both Canada and the U.S. (Guédon, 1989, pp.
Telidon then cannot be seen solely as the pawn of big business nor as the handmaiden of technological determinists.

 Telidon   (Site not responding. Last check: 2007-10-29)
Telidon (from the Greek words tele "distant" and idon "I see") was the first videotex software to employ alphageometric graphics, a much less "blocky" improvement over the alphanumeric graphics used in Britain and most of Europe.
Telidon, combined with developments of ATandT in the U.S. in the early 80's evolved into the North American Presentation Level Protocol System (NAPLPS), the industry standard until the invention of the World Wide Web and Hypertext Markup Language.
Experimental use of Telidon began in 1977 and the first bona fide field trials began in 1979.

Telidon did produce NAPLPS, and this code is far from dead--it has only been asleep waiting for the world to catch up with it--working in the ``background'' as they say in UNIX.

Telidon was so impressive that ATandT decided it wanted in on the project.
Various systems using NAPLPS appeared in the early 1980s, but it soon became clear that there was no way to make money on a read-only service (a fact many in the web discovered again 20 years later).
In the 1980s it became the basis for the GKS microcomputer based standard, which was later implemented in Digital Research's GSX graphics system and later used in their GEM GUI.

 Telidon
Telidon, a combination of the Greek words meaning "to know at a distance," was a waypoint en route to the Internet and was an early demonstration of how technology can provide on-demand access to information.
It was developed by researchers in the federal Department of COMMUNICATIONS in Ottawa in the mid-1970s, combining aspects of television, the TELEPHONE and the computer to produce a new medium of communication and information processing.
There were 3 major ways to implement Telidon systems: videotex, teletext and as stand-alone systems; and there were significant differences in the capabilities of the resultant systems.

In addition to the hardware items already mentioned - the television set, the telecommunications link, and the computer - a decoder was required to accept the coded instruction from the computer and generate an electronic signal that creates the display on the screen.
When Telidon was first announced in 1978, videotex activity in Europe was already gaining momentum and predictions about videotex services becoming almost a necessity in every home within a few years were rampant.
The inventors of Telidon received several awards for the important contribution they made to the development of information technology in Canada.

 Videotex -- Facts, Info, and Encyclopedia article   (Site not responding. Last check: 2007-10-29)
Telidon split the data flow in two, using both the TV signal and the telephone.
The TV signal was used in a similar fashion to Ceefax, but used more of the available signal (due to differences in the signals between North America and Europe) for a data rate about 1200 bit/s, while using a low-speed modem on the phone line for menu operation.

Drawing on archival data and interviews conducted during fall 2001, this project explores the history and afterlife of the Telidon Program, an ambitious national videotex program spearheaded by the now-defunct Canadian Department of Communication in the late 1970s and early 80s.
Telidon, its proponents say, was a project ahead of its time, prefiguring many of the functions and visions of connectivity that have subsequently come to be associated with the Internet.
Its detractors write the program off as a failure, built on an unworkable model of government/industry relations and an excessively centralized vision of social computing already, by the early 80s, giving way to the PC revolution.
