Teletext
Teletext
(not to be confused with the current ITV and Channel Four text
contractor – back then the word teletext was a generic term)
was one of the success stories of the 1985 yearbook. What had
been introduced as an experimental service just ten years ago
(in July 1975), and only come fully into service in 1977, was
now a reality in 2million homes, with the average viewer
spending at least 2 hours per week looking at teletext.
To
reflect this, in 1984 (the year that the 1985 yearbook covers)
the transmission lines made available to teletext was increased
to six, vastly improving the speed of the service.
Teletext
on ITV and Channel Four was provided by ORACLE, a company born
out of the group of engineers who jointly developed the system
with the BBC and owned by all of the ITV companies. In 1984, the
system they developed together was used by 98% of the world’s
television services. The IBA was justly proud of its
contribution to the development of teletext.
It
is notable that subtitling had not yet settled on the familiar
page "888", and was available on page 170 on ITV and
470 on Channel 4. There were three full regional teletext
centres in operation in 1984 – in the Scottish Television,
Channel Television and LWT/Thames regions, that could broadcast
their own advertising and editorial. Back in 1984 far fewer
programmes were subtitled than now, and live programmes, such as
the news, were not subtitled.
This
service was expanded on the 2nd April 1984, with
mini-computers installed in all of the remaining regions
allowing them to broadcast a limited regional teletext service.
It is interesting to note that back in 1984 regional pages were
not available when TV-am was on air. |
