Season 18



The eighteenth season of Doctor Who ran between 30 August 1980 and 21 March 1981. It was Tom Baker's final season. It was also the first season of John Nathan-Turner's producership. Many of the changes he brought in during this season would continue throughout the 1980s — some to the end of Doctor Who's original run. Amongst the more obvious changes during the season were: a new logo, a reworking of the theme tune, fully electronic incidental music, a raft of new writers and directors and the introduction of the question mark motif on the Doctor's clothing. Finally, it was Barry Letts' swansong on the programme. He had returned for this one year to executive produce.

Overview
Season 18 consisted of seven stories and twenty-eight episodes. It was the last season of the original series to have an autumn-to-spring broadcast schedule and the last to have an autumn start until Season 23. After this season, the number of episodes per season began to decline, after a relatively stable episode count for the whole of the 1970s.

From Full Circle onwards, the season featured a story arc involving E-Space and the return of the Master. The stories were darker and more adult in tone than those during the Graham Williams era. They also attempted to emphasise science, much to the satisfaction of both script editor Christopher H. Bidmead and executive producer Barry Letts. (REF: The Fourth Doctor Handbook)

From a ratings standpoint, it sits right at the very nadir of Doctor Who history. It is easily the worst-ranked season of Doctor Who, with 17 of its 28 episodes outside of the top 100 shows. Indeed, the 9 lowest-charting episodes in Doctor Who history come from this season. Full Circle's second episode remains the worst-charting episode of Doctor Who. Its paltry 3.70 million viewers were only good enough for what was, even by the season's low standard, an extremely anaemic 170th place during the week of 1 November 1980. In terms of pure ratings, as opposed to ranking, it was not quite the worst of the lot. But it was easily the least-watched Tom Baker season, with an average of only 5.8 million Britons watching each episode. (REF: The Fourth Doctor Handbook) The decline in ratings has been attributed to direct competition from ITV. The first half of the season was up against Buck Rogers in the 25th Century, an American import with considerably better production values. (INFO: Full Circle)
