The episode was broadcast by the public broadcast company NOS on the state owned channel Nederland 1, in the timeslot 15:35-16:25 (though the timeslot could shift up, and downwards by as much as 10 minutes later on in the series run) on Sunday on a weekly basis. As usual in The Netherlands, the episodes were not dubbed, but subtitled and over the course of nearly one year, about half of the series was broadcast. However, as with Flanders, the episode titles were translated into Dutch in their TV guides. Neither Dutch nor Flanders TV followed the American broadcast or production order, but broadcast episodes from all three seasons in a rather haphazard order. Unlike the 1971 false start, the NOS follows through with the series, broadcasting approximately half of the original 79 episodes in one continuous run. At the time state-owned both nation's channels did not use the commercial break format.
