Overpriced box you can hook up to your BBC microcomputer that lets it receive teletext broadcasts. Since the beeb already has a teletext text mode (aka MODE 7), this is not as horrible as it could have been. Also, programs for the BBC were broadcast by the BBC. Of course, the teletext protocol still had tremendous latency, and the beeb's memory wasn't large enough to do significant caching, so it wasn't that much fun.

The limitations of the teletext technology, combined with the high price of the adaptor, help explain why it sank faster and deeper than teletext itself.
