Antiope (1976/1979) was the French competitor to the British teletext standard. Antiope used a higher data rate, dynamic page sizes, custom fonts, and generally more sophisticated graphics, although some of these features were introduced later in the 1980s.
According to the French, it was not as “crude and old fashioned” as British teletext. Nevertheless, the British won the the standardization war and proclaimed World System Teletext, while Antipoe was used for Teletel (better known as Minitel).
