Episodes continued to be broadcast weekly until mid-1966, generally in the same timeslot for each city that the programme had debuted in the previous year. By the time the last weekly episode was broadcast in June 1966 – episode 4 of "The Crusade" – first-run ABC episodes were still only around twelve months behind their original BBC transmission dates. In October 1966 the first episode of "The Space Museum" marked the first time the ABC stripped Doctor Who in the 6:30 Monday–Thursday timeslot. With only occasional changes or minor variations to days and times, the ABC continued to strip "Doctor Who" in a weekday early-evening timeslot for much of the next twenty-six years. Later in 1966 the ABC also started showing repeats of chunks of the most recent first-run stories in the same stripped prime-time slot. (Repeats not only remained commonplace, but their regularity also went on to generate fan dissatisfaction by the early 1980s).
