The pattern of new episodes and repeats continued, with more-or-less uninterrupted broadcast of "Doctor Who" throughout the ratings periods of 1982, 1983 and 1984, including numerous black and white Pertwee serials unscreened for ten years. In 1985 "Doctor Who" didn't return to the ABC until the premiere of Colin Baker's first full season in early December. On its original UK broadcast, Season 22 featured a change in format to 45-minute episodes. However, to fit with established scheduling here in Australia, the ABC cut each 45-minute episode in half, resulting in two roughly 23½ minute episodes and meaning a particularly poor 'non-cliffhanger' was created at around the halfway mark of each of the original episodes.
