premise: 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).
hypothesis: The Magic Roundabout was a children's television show created and broadcast in 1964.
reason: The text states that The Magic Roundabout was created in 1963. I conflated the information about the show being broadcast in 1964 with the information about it being created and fooled the system into thinking both happened in the same year.
