What-is-what-TV

→ Main article : What is what TV

According to the principle of the non-fiction book series, various factual topics were dealt with in a child-friendly and media-friendly manner. From 1983 to 1984 there was a 20-minute television broadcast on First German Television , moderated by Heinz Haber . After a break of several years, the concept was revived in a modified form as “Was ist Was TV”. From 2001 to 2009, 52 episodes were produced in two seasons of 30 minutes each.

Radio plays

The radio play series is based on the editions of the television program and was produced with the same voice actors: the narrator and Quentin were voiced by Crock Krumbiegel , the votes for Theo and Tess were given by Jakob Riedl and Anna Carlsson, respectively. From around 2012 the series was formally revised. The series, which consisted of double episodes throughout, has been partially recompiled, whereby it can be seen that the individual titles have been grouped more closely than before on related topics. Since the subjects "cats" and "horses" had been dealt with twice before, a complete double episode was left in the course of the new composition.
