Sounds like Teletext was basically a digital-magazine protocol. This is, a TV-station would continuously broadcast the latest Teletext-magazine for Teletext-clients to cache. Then users could view articles from their local cache. Reference: https://en.wikipedia.org/wiki/Teletext https://en.wikipedia.org/wiki/Teletext EDIT: Apparently most implementations wouldn't cache something until the user requested it, then the user would wait until the next send.

  Not the same. Teletext' content was on the signal and it changed daily. That's it, a continous stream. There was no stored data.

Teletext was like a newspaper sent on vblank cycles. You also had a reveal button in order to show some puzzle games'/riddles' solution.

IIRC the more "modern" TVs did have some sort of cache for Teletext pages, but my memory is definitely hazy...

Some TVs would show you which page was currently being sent in addition to the page number you were currently viewing. It went up sequentially, starting at 100 (which was the "home page"). That way you could time typing in the number (I remember on Ceefax 601 was the TV listings for BBC1) - say when it was at around 540 - and then you wouldn't have to wait so long for the page to "load". Most pages had multiple "sub-pages" - so the BBC TV listing would start in the morning, as 1/5 - then on each refresh, it would show 2/5, 3/5 etc. If you really wanted to study a particular page before it would reload, there was often a "Hold" button that paused the refreshes. Then, when you "un-held" it would jump to whichever page was sent on the next update. Watching the scores on a Saturday afternoon, updating across the various leagues, was a ritual for every football fan. (Maybe page 302 for football scores?) Bamboozle was page 451 on Channel 4 - everyone loved that.

  holy crap, thanks for the memories! I remember bamboozle, and also, I think on Channel 4, the "Tea Time Quiz", where you had to answer a question and be the first to phone in the correct answer, I remember winning on a couple of occasions!
