Doctor Who is a British science fiction television programme produced by the BBC. As of 22 June 2024,[update] 883 episodes of Doctor Who have aired. This includes one television movie and multiple specials, and encompasses 311 stories over 40 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.[1]
Doctor Who ceased production in 1989 after 695 episodes. A one-off TV movie was produced in the US in 1996, before the series resumed in 2005. The original series (1963–1989), generally consists of multi-episode serials; in the early seasons, and occasionally through its run, serials tend to link together, one story leading directly into the next. 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.
For the first two seasons of Doctor Who and most of the third (1963–1966), each episode carries its own title; the show displays no titles for overarching serials until The Savages, at which point the episodic titles cease. The titles below, for these early serials, are those in most common circulation, used for commercial releases and in resources such as the Doctor Who Reference Guide and the BBC's classic episode guide. With the show's revival in 2005, the programme returned to individual episode titles.
Due to the BBC's 1970s junking policy, 97 episodes of Doctor Who from the 1960s are no longer known to exist. As a result, 26 serials are currently incomplete, with one or more episodes represented only by audio, which in many cases is in addition to clips or still frames. For commercial release, some episodes have been reconstructed using off-air audio recordings, paired to surviving visuals or newly commissioned animation.
The story numbers below are meant as a guide to placement in the overall context of the programme.[2] 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,[3] and whether the unfinished serial Shada should be included.[4] The numbering scheme in this list follows the official website's episode guide.[2] 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).
The following table dictates the season or series in question for the programme as a whole.

Notes
- The First Doctor remained for the first two serials of season 4. The Second Doctor featured for the remainder of the season from the third serial, The Power of the Daleks.
- Also known by its subtitle, The Key to Time
- Shada was left unfinished due to a strike. The story was later completed and officially released on home media in 2017. The voices of the original actors with new animation was incorporated to bridge the gaps between the recorded live-action segments. It is not included in the episode or story counts as it was not broadcast.
- The Fifth Doctor regenerated in the sixth serial of season 21. The Sixth Doctor featured only in the final serial, The Twin Dilemma.
- Also known by its subtitle, The Trial of a Time Lord
- Also known by its subtitle, Flux
- This episode was the first episode of the twelfth series (and is only counted in the § Regular seasons table of this article), and thus not a special aired outside of a series, but it was aired four days before the twelfth series' traditional timeslot in order to air deliberately on New Year's Day.
First Doctor
The first incarnation of the Doctor was portrayed by William Hartnell. During Hartnell's tenure, the episodes were a mixture of stories set on Earth of the future with extraterrestrial influence, on alien planets, and in historical events without extraterrestrial influence, such as Marco Polo, one of the lost serials. In his last story, The Tenth Planet, the Doctor gradually grew weaker to the point of collapsing at the end of the fourth episode, leading to his regeneration.

Second Doctor
The Second Doctor was portrayed by Patrick Troughton, whose serials were more action-oriented than those of his predecessor. Additionally, after The Highlanders, stories moved away from the purely historical ones that featured during William Hartnell's tenure; instead, any historical tales also included a science fiction element. Patrick Troughton retained the role until the last episode of The War Games when members of the Doctor's race, the Time Lords, put him on trial for breaking the laws of time. The Doctor was forced to regenerate and thereafter exiled on Earth.
Season 4 (1966–1967) continued
This season introduced companions Jamie McCrimmon (Frazer Hines) and Victoria Waterfield (Deborah Watling), in The Highlanders and The Evil of the Daleks, respectively. Ben and Polly departed in The Faceless Ones.

Third Doctor
The Third Doctor was portrayed by Jon Pertwee. Sentenced to exile on Earth and forcibly regenerated at the end of The War Games, the Doctor spent his time working for UNIT (United Nations Intelligence Taskforce). After The Three Doctors, the Time Lords repealed his exile; nevertheless, the Doctor still worked closely with UNIT from time to time. The Third Doctor regenerated into his fourth incarnation as a result of radiation poisoning in the last moments of Planet of the Spiders.
Season 7 (1970)
From this season onwards the programme was produced in colour. To accommodate the new production methods the number of episodes in a season was cut: season 6 has 44 episodes; season 7 has 25 episodes. The seasons continued to have between 20 and 28 episodes until season 22. This season featured companion Liz Shaw played by Caroline John.

Fourth Doctor
The Fourth Doctor was portrayed by Tom Baker. He is, to date, the actor who has played the Doctor on television for the longest period of time,[17] having held the role for seven seasons.
Season 12 (1974–1975)
All serials in this season continue directly one after the other, tracing one single problematic voyage of the TARDIS crew. Despite the continuity, each serial is considered its own standalone story. This season also introduced the character of Harry Sullivan portrayed by Ian Marter as a companion; this character was intended to undertake action scenes, during the period prior to Tom Baker being cast, when it was unclear how old the actor playing the new Doctor would be.

Season 18 (1980–1981)
In a return to the format of early seasons, virtually all serials from Seasons 18 through 20 are linked together, often running directly into each other. Season 18 forms a loose story arc dealing with the theme of entropy. Full Circle, State of Decay, and Warriors' Gate trace the Doctor's adventures in E-Space; they were released in both VHS and DVD boxsets with the umbrella title The E-Space Trilogy. This season saw the departure of Romana and the introduction of companions Adric and Nyssa, and soon-to-be companion, Tegan Jovanka.
