There are apps that show teletext which, acording to some, are quite popular. It does somehow fit into a retro scifi aesthetic too if one’s into that kind of thing 😄
Back in the day, I had an application that could decode teletext from a TV capture card. And there are PC based DTV receivers that can also do that.
And over here in Finland, the national public broadcaster has the teletext on web. (Yle is the last network to put any effort in teletext - the commercial channels like MTV3 and Nelonen used to have a whole bunch of teletext stuff like premium SMS based chats, but those aren’t really all that profitable these days. I think MTV3 still has that, but they’re shutting it down next year.)
