List of ''Doctor Who'' serials

Doctor Who is a British science fiction television programme produced by the BBC. As of 1 July 2017, 839 episodes of Doctor Who have aired, concluding the tenth series. This includes one television movie and multiple specials, and encompasses 275 stories over 36 seasons. 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] In June 2017, it was announced that due to the terms of a deal between BBC Worldwide and SMG Pictures in China, the company has first right of refusal on the purchase for the Chinese market of future series of the programme until and including Series 15.^[2][3]

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. 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,^[4] and whether the uncompleted Shada should be included.^[5] The numbering scheme used here reflects the current internal practice of describing "Planet of the Dead" (2009) as the 200th story, used in the 407th issue of Doctor Who Magazine.^[6] Other sources, such as the DVD releases of classic Doctor Who serials in Region 1, use different numbering schemes, which diverge after the 108th story, The Horns of Nimon (1979–1980).

Episodes

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.

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,^[8] 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.

Season 23 (1986)

After an 18-month production hiatus, the series returned. Eric Saward was script editor for parts 1-8 and 13; Nathan-Turner unofficially script edited parts 9-12 and 14 because of Saward's sudden 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^[10] (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".

Ninth Doctor

In 2005, the BBC relaunched Doctor Who after a 16-year absence from episodic television, with Russell T Davies, Julie Gardner and Mal Young as executive producers, Phil Collinson as producer, and Christopher Eccleston taking the lead role of the Ninth Doctor.

The revival is a continuation of the original series. The new series is formatted to a 16:9 widescreen display ratio, and a standard episode length of 45 minutes. For the first time since the 1965/66 season each episode has an individual title, although most stories do not span more than one episode. The show also returned to its traditional Saturday evening slot.

Series 1 (2005)

The 2005 series constitutes a loose story arc, dealing with the consequences of the Time War and the mysterious Bad Wolf.
