A year later, https://en.wikipedia.org/wiki/File_Retrieval_and_Editing_Sys... got a bit more ‘net’ (https://www.brown.edu/news/2016-05-23/hypertext has a movie about it that is worth watching but unfortunately doesn’t show how it worked). At least, it supported multiple terminal types. That page also claims “FRESS still runs on the current Brown mainframe.” Iet would be amazing if that were true. Software that’s over 50 years old.
Pr. Wikipedia, in 2015 9% of the Norwegian population used teletext. In 2017, that number had reduced to 7.5% - I suspect those are mostly old folks.
But to be fair, it was incredibly handy to look up specific things fast. If you wanted sports / betting results, TV-program, currencies, or whatever, you probably had memorized the page number.
