If I had to know what was on TV this was the best way. The only other way for me was to check the paper with the TV listings or some magazine, and teletext was just infinite times better to check
Not the person you asked, but it was very popular in the UK. You could get news, sport, programme times, recipes, reviews, games, holidays and all sorts. With no on demand TV it was often more interesting than what was currently being broadcast. It was also the basis for displaying subtitles over TV.
At the time I think in most western Europe teletext was a thing. Imagine you had this menu on the TV with pages that have graphics of the Atari 2600, and you access by inserting 3 digits codes on the page, seeks the page for you, and presents what's in there. This was, in a nutshell, teletext
At some point much later teletext even go a chat function. Was with SMS, extremely expensive.Soome people went ham on the relationships zone (and at some point there was also a 18+ zone for dirty talk during the night)
The data for the pages was contained in the "flyback"; each dot of each frame of your normal TV programme image started at the top left of the screen, moved to the right and then flew back to the left, one line down until you had a screen's-worth. The flyback was fast so as to get a full screen image in whatever the frame rate was (30Hz?) Originally the flyback was just wasted bandwidth: a necessary loss whilst your TV moved it's electron beam back to the left hand side. But because the flyback was fast, you'd never be able to get a full 'proper' image in there; that's why teletext was text and primitive block graphics. And why you'd have to wait several minutes to see the page you wanted on a trend page cycle!
TV Guide. Every week, you’d get a little digest in the post with a listing of that week’s shows, trivia, Q&As and interviews with insiders, and puzzles & games. I was very interested in movies and television, and devoured it cover to cover.
