 The concept of the series was developed and produced from 1969 as a successor of the children's series ""Spielschule"" and shot in Munich, because the BR managers considered, that the social situation in Germany was not correctly represented by "Sesamstraße" and therefore needed a replacement program.In the show a red minibus, equipped as a camera car, drove across the country and showed encounters with people and their stories.At the beginning of the series the "Spielmobil was" an Opel Blitz.
