List of Doctor Who serials

Doctor Who is a British science fiction television programme produced by the BBC. As of 25 December 2015, 826 episodes of Doctor Who have aired, concluding the ninth series. This includes one television movie, and encompasses 263 stories over 35 seasons. Additionally, four charity specials and two animated serials have also been aired. The show's high episode count resulted in Doctor Who holding the world record for the highest number of episodes for a science-fiction programme.^[1]

Doctor Who ceased airing in 1989 and began again in 2005. Each story in the original series (1963–1989) is a multi-episode serial, with two exceptions: the 1965 cutaway episode "Mission to the Unknown" and the 20th anniversary story The Five Doctors. The characters in the column after the serial titles indicate the code used by the production team to designate the serial, where applicable, and are followed either by the titles of the individual episodes where given or by the number of episodes otherwise. During the early seasons of the programme, and occasionally through its run, most serials were linked together; usually one story would lead directly into the next. Starting with the 2005 revival, the production team abandoned the traditional serial format for a largely self-contained episodic format with occasional multi-part stories and loose story arcs.

Due to the BBC's 1970s junking policy, 97 episodes from the 1960s are missing, with the result that 26 serials are incomplete, although all of these still exist as audio recordings, and some have been reconstructed. In the first two seasons and most of the third, each episode of a serial had an individual title; no serial had an overall on-screen title until The Savages. The serial titles given below are the most common title for the serials as a whole, used in sources such as the Doctor Who Reference Guide and the BBC's classic episode guide, and are generally those used for commercial release. The practice of individually titled episodes resurfaced with the show's 2005 revival, when Doctor Who's serial nature was abandoned in favour of an episodic format.

The story numbers are not official designations but are merely to serve as a guide to where the story stands in the overall context of the programme. There is some dispute about, for example, whether to count Season 23's The Trial of a Time Lord as one or four serials,^[2] and whether the uncompleted Shada should be included.^[3] The numbering scheme used here reflects the current internal practice of describing "Planet of the Dead" (2009) as the 200th story, used in the official magazine's 407th issue.^[4] Other sources, such as the Region 1 DVDs of classic Doctor Who serials, use different numbering schemes which diverge after the 108th story, The Horns of Nimon (1979/80).

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.

Season 1 (1963–1964)

Verity Lambert was producer with David Whitaker serving as script editor.

John Wiles replaced Verity Lambert as producer after Mission to the Unknown. Innes Lloyd, in turn, replaced Wiles after The Ark.

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 and forced him to regenerate.

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 time,^[7] having held the role for seven seasons.

Season 12 (1974–1975)

Barry Letts served as producer for Robot, after which he was succeeded by Philip Hinchcliffe. Robert Holmes took over from Terrance Dicks as script editor. 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 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.

John Nathan-Turner replaced Graham Williams as producer. Barry Letts returned, as executive producer, for just this season. Christopher H. Bidmead replaced Douglas Adams as script editor. 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.

Season 23 (1986)

After an 18-month production hiatus, the series returned. Eric Saward was script editor up to part eight, when Nathan-Turner unofficially took over script editing the remainder of the season because of Saward's departure. The whole season is titled as The Trial of a Time Lord, and is split into four segments. The segments are commonly referred to by their working titles^[9] (listed below) but the season was broadcast as one fourteen-part story and the working titles did not appear on screen. Episode length returned to 25 minutes, but with only fourteen episodes in the season, making the total running time of this season (and subsequent seasons) just over half of the previous seasons, going back to season 7.

Eighth Doctor

The Eighth Doctor was portrayed by Paul McGann. The movie is the only television appearance of this Doctor during his tenure. The only production title held by this story was Doctor Who. However, producer Philip Segal later suggested Enemy Within as an alternative title. Lacking any other specific name, many fans have adopted this to refer to the movie. Fan groups have also used other informal titles. The DVD release is titled Doctor Who: The Movie. In 2013, Paul McGann returned for the second television appearance of the Eighth Doctor in the minisode titled "The Night of the Doctor".
