The Magic Roundabout (known in the original French as "Le Manège enchanté") was a French-British children's television programme created in France in 1963 by Serge Danot, with the help of Ivor Wood and Wood's French wife, Josiane. The series was originally broadcast from 1964 to 1974 on ORTF (Office de Radiodiffusion Télévision Française).
The Magic Roundabout is still being shown on tv.
Even though it was broadcast in 1964-1974, we cannot assume a station does not show it. The system is assuming the original broadcast date and not accounting for reruns.
