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

I actually saw a recording of a news story about that recently. It was about when BBC's Ceefax shut down 12 years ago.

It was interesting because I'd never hear of something like that before. I guess the technology wasn't too big in the US.
