ORACLE and CEEFAX have argued as to who was first. It seems that Oracle were the first to demonstrate their system to the public, whereas Ceefax were the first on-air.
From an IBA yearbook: "IBA and ITV engineers are proud of the fact that the very first 50-page computer-edited teletext magazines were demonstrated to an audience of distinguished guests over the IBA's Crystal Palace transmitter on the 9th April 1973. This was the first such demonstration anywhere in the world of the system that has since been further developed and is now often known as teletext.
"ORACLE was developed in 1972-1974 by IBA engineers and subsequently became part of the British teletext standard adopted throughout the world. From 1974 it was provided as a service by ITV with editorial teams at LWT and ITN."
This picture shows that first public demonstration system. Note that it is text only, there was no evidence of colour, a clock, or in fact anything really!
Incidentally, the name ORACLE is derived from the acromym of Optional Reception of Announcements by Coded Line Electronics.
probably date from slightly later. We see the same clunky-looking 'remote'
control and also show what's on the screen quite clearly.

pages are reconstructed by Andrew Wiseman from the IBA Radio and TV
Yearbooks and they date from 1980.
Originally these pages were all broadcast sequentially, in the order 1xx, 2xx, 3xx, 4xx, 2xx, 7xx. This was done in order to favour the ITN news pages which were the most popular. Later, as more data lines were made available the magazines were given dedicated data lines and broadcast concurrently.
In those days the tv pages were not regionalised, so Oracle had to carry a page for TV, Weather and What's On for each of the ITV companies. (Although London What's On had its own section.)

Andrew Wiseman recalls:
|Very early experiments in hi-res (well
higher res!) teletext from 1980. Level 2 Teletext finally made it into spec by the early
1990's, but apart from experiments, it wasn't adopted by UK teletext providers.
Some other ORACLE milestones:
|From 1982 onwards with the birth of
Channel 4, Oracle moved the City pages to Channel 4.
This particular example is from 1989. This tradition was carried on by Teletext when it took over in 1993.
date from 1987.
The fact that the ORACLE service is now spread across two channels is now reflected in the revised index page.
The traditional Saturday night dross is on offer from ITV and it is noticeable that throughout the evening only two programmes were subtitled.
|The Tech page comes from Oracle's
"BUZZ" magazine in 1989.
Andrew Wiseman suggests that Ceefax have stolen the name for their new Childrens / Entertainment pages.

TTAN contributor Bryan Green says "This was a test for the first animated selection due to go out in-vision on Channel 4 from Mon 14 September 1987."
These two versions are from frames recorded in Feb 1989. The first is animated at one frame every 5 seconds, which is probably how it was transmitted, but the second version is somewhat faster!

Two versions, apparently from the same day. I think perhaps the second one was put together specially for a demonstration.

Can anyone tell us how this service worked?
