Doctor Who is a BBC drama series and the longest-running science-fiction programme in worldwide TV history. The show was first broadcast in 1963, when a series would run for almost the entire year. By the 1970s, this was reduced to a run of about five months and by the 1980s it was down to just 14 weeks a year.

This entry divides the stories into 'seasons'; each season covers all of the episodes shown within one transmitted block of episodes. The original series ran for 26 seasons up to 1989. This entry also lists the three Doctor Who productions that were transmitted between 1993 and 1999, although only the TV Movie is classed as an official story. We have also included information on the revived series, which began in 2005. Although this 2005 revival is generally classed as 'Series One', the intention is that it is a continuation of the original series, hence its presence here.

Note: The story titles supplied here are, in some places, based on a combination of sources. The first stories, up to and including 'The Gunfighters', did not have on-screen overall story titles and there remains some debate as to the 'proper' titles for some stories. For the first three stories there are no absolute 'right' titles - despite some people insisting otherwise, but to save argument, we've gone with the titles that appear in the files at Doctor Who Magazine. That does not prevent you from referring to the first story as 'An Unearthly Child'; we consider it basic good manners to allow fans to stick to the titles they know rather than enforcing one title over another.

But when they discover that the Guardian of the Solar System, Mavic Chen, is among the delegates, the Doctor and his friends steal the vital Taranium Core from the Daleks' Time Destructor and flee the planet using Chen's ship with the intention of warning the people of Earth that they have been betrayed.

Landing Chen's ship on the prison planet Desperus while they get their bearings, the travellers are unaware that the ship has acquired a stowaway, a convict called Kirksen, who holds Katarina captive to prevent the ship from going to Earth. As the Doctor and Steven try to persuade Vyon to give in to the convict's demands, Katarina pulls a lever inside the airlock and both she and the convict are pulled out into deep space towards certain death.

Vyon is also killed by another Space Security agent - his own sister, Sara Kingdom, who had been told by Chen that Vyon was a traitor. When she learns the truth of Chen's treachery, she joins the Doctor and Steven in their quest to thwart Chen's plans. The trio return to Kembel to collect the Tardis and from there they escape in time, doggedly pursued by the Daleks in one of their own time ships.

As the Doctor and Jamie wave goodbye to Ben and Polly, they see the Tardis being taken away on the back of a lorry. The limited trail of clues lead the Doctor and Jamie first to an antiques shop, then to a large country house in the year 1866 where two scientists, Maxtible and Waterfield, are being forced to conduct experiments for a higher power that is holding Waterfield's daughter Victoria hostage. The Doctor is shocked to learn that this higher power is the Daleks, but that is nothing compared to his surprise when the Daleks insist that he help the scientists with their experiments to identify a 'human factor' - with Jamie as their test subject. But why do the Daleks need a human factor? And what does this have to do with the Dalek Emperor, who sits in the heart of the Dalek city on Skaro?

Note: New companion Victoria (Deborah Watling) was introduced in this story. Original Dalek voice artist Peter Hawkins performed his duties here for the final time, while Roy Skelton voiced the first of many Daleks for the series.
