Cancellation
The show's axing, announced in mid-1972, was highly controversial—not least because it was replaced by the American program Sesame Street -- and an unprecedented flood of public protest ensued.

However the campaign was unsuccessful and the final episode, number 1175, aired on 22 December 1972.
