Teletext decoder test on national Czech TV, Česká Televize, 2024. One in ten Czechs accessed ČT1 teletext in 2009, according to this report. ČT announced a new teletext service in 2010 and launched “HD teletext” (HbbTV) the following year, while still keeping the oldschool one.
Time Teletext was a US teletext service, 1981-1983. Compared to common British teletext, Time offered smooth vector graphics with the NAPLPS-standard (common in American videotex).

BB – a demo for Unix and DOS made by four Czech teenagers in 1997: Jan Hubicka, Kamil Toman, Mojmir Svoboda and Filip Kupsa. They made a notorious library for ASCII-conversion, AA-lib, which was later used for example in Hasciicam and VLC (see Wikipedia). They also made Aview that lets you browse the web in ASCII, ASCII-3D-2000 that creates stereogram ASCII, and more. It’s a similar spirit to the ASCII Art Ensemble.

This is the TBT-03 keyboard by Loewe, for the MCT 26 television. Circa 1984. It is used for the German videotex format BTX (and possibly other similar CEPT-standards like the Mupid?). Found here. Also see the TBT-02 keyboard
