Teletext R Podcast, 12 December 2020 – Behind Vertical Bars: Prisoners and Coded Teletext Messages

Recently, Spanish prisoners have hit the international headlines for their use of teletext to communicate with the outside world. But, as Dan and Carl find out, this certainly isn’t the first time this sort of thing has happened.

In a Teletext R Podcast special feature, teletext fan Thomas Boevith presents his elightening research into Copenhagen prisons’ internal teletext services.

And finally, we take a look at a few other coded messages in teletext and the general media.
