List of Doctor Who episodes (2005–present)
<onlyinclude>"Doctor Who" is a British science fiction television programme produced by the BBC. This includes one television movie and multiple specials, and encompasses stories over 39 seasons, starting in 1963. Additionally, four charity specials and two animated serials have also been aired. The programme's high episode count has resulted in "Doctor Who" holding the world record for the highest number of episodes of a science-fiction programme.</onlyinclude> In May 2017, it was announced that BBC Worldwide sold the right of refusal on future series of the programme until and including  series 15 in China. "Doctor Who" ceased production in 1989, then resumed in 2005. The original series (1963–1989), generally consists of multi-episode serials. The 2005 revival trades the earlier serial format for a run of self-contained episodes, interspersed with occasional multi-part stories and structured into loose story arcs. The story numbers below are meant as a guide to placement in the overall context of the programme. There is some dispute, for instance, about whether to count Season 23's "The Trial of a Time Lord" as one or as four serials, and whether the unfinished serial "Shada  should be included. The numbering scheme in this list follows the official website's episode guide. Other sources, such as the Region 1 classic Doctor Who" DVD releases, use different numbering schemes, which diverge after the 108th story, "The Horns of Nimon" (1979–1980). Series overview.
