'''Season 16''' of ''[[Doctor Who]]'', also referred to as '''''The Key to Time''''', ran from [[2 September (releases)|2 September]] [[1978 (releases)|1978]] to [[24 February (releases)|24 February]] [[1979 (releases)|1979]]. It starred [[Tom Baker]] as the [[Fourth Doctor]], [[Mary Tamm]] as [[Romana I]] and [[John Leeson]] as [[K9 Mark II]]. The season opened with ''[[The Ribos Operation (TV story)|The Ribos Operation]]'' and concluded with ''[[The Armageddon Factor (TV story)|The Armageddon Factor]]''.


Season 16 marked a triple milestone for ''Doctor Who'': the hundredth story (''[[The Stones of Blood]]''), the five-hundredth episode (episode 1 of ''[[The Armageddon Factor]]'') and the fifteenth anniversary of the first broadcast, on November 23, 1978.
== Overview ==
It consisted of six serials comprised of twenty-six episodes. This season saw the introduction of the [[Black Guardian|Black]] and [[White Guardian]]s as well as the companion Romana I who became the first [[Time Lady]] companion since [[Susan Foreman|Susan]]. This season is sometimes colloquially known as ''The Key to Time'' season after the story arc involving the [[Key to Time]]. Although not the first season to consist of linked stories ([[Season 8 (Doctor Who 1963)|Season 8]] in [[1971 (releases)|1971]] was the first, as all the stories that year featured {{Delgado}}), it was the first to be recognised as having a series-long arc. Although multi-serial arcs would occur again, such a full-season experiment wouldn't be attempted again until [[Season 23 (Doctor Who 1963)|Season 23]]. The arc has a number of similarities to the Season 1 story ''[[The Keys of Marinus (TV story)|The Keys of Marinus]]''. The storyline was originally proposed for Season 15, but it required more planning.<ref>http://www.shannonsullivan.com/doctorwho/serials/5a.html</ref>


In 2002 (Region 1) it became the first ''Doctor Who'' season to be released to DVD in its entirety in a single box set; it remained the only "classic series" season to be available as a single set until the release of [[Season 23]], ''[[The Trial of a Time Lord]]'' to DVD in [[2008]].

A number of publicity photos for the season show Tom Baker sporting a very obvious bandage on his upper lip; this was due to his being bit by a dog shortly before filming for the season began. The resulting lip injury is visible to varying degrees throughout the season.

Season 16 of Doctor Who, also referred to as The Key to Time, ran from 2 September 1978 to 24 February 1979. It starred Tom Baker as the Fourth Doctor, Mary Tamm as Romana I and John Leeson as K9 Mark II. The season opened with The Ribos Operation and concluded with The Armageddon Factor.

Overview[[edit] | [edit source]]

It consisted of six serials comprised of twenty-six episodes. This season saw the introduction of the Black and White Guardians as well as the companion Romana I who became the first Time Lady companion since Susan. This season is sometimes colloquially known as The Key to Time season after the story arc involving the Key to Time. Although not the first season to consist of linked stories (Season 8 in 1971 was the first, as all the stories that year featured the Master), it was the first to be recognised as having a series-long arc. Although multi-serial arcs would occur again, such a full-season experiment wouldn't be attempted again until Season 23. The arc has a number of similarities to the Season 1 story The Keys of Marinus. The storyline was originally proposed for Season 15, but it required more planning.[1]

Season 16 marked a triple milestone for Doctor Who: the hundredth story (The Stones of Blood), the five-hundredth episode (episode 1 of The Armageddon Factor) and the fifteenth anniversary of the first broadcast, on 23 November 1978.

A number of publicity photos for the season show Tom Baker sporting a very obvious bandage on his upper lip; this was due to his being bit by a dog shortly before filming for the season began. The resulting lip injury is visible to varying degrees throughout the season.

In 2002 (Region 1) it became the first Doctor Who season to be released to DVD in its entirety in a single box set; it remained the only "classic series" season to be available as a single set until the release of Season 23, The Trial of a Time Lord to DVD in 2008.

Tom Baker decided to leave by the end of this season, but he was persuaded to stay.[2]
