Question: How many seasons did Doctor Who run for?
About the article "Doctor Who", section "Episodes".

Candidate passages:
As with the television series, the William Hartnell version of the Doctor was the original comic strip Doctor.
However, the actor's portrayal of the character was often lost in TV Comic, the dominant publication to feature First Doctor stories.
At a superficial level, the character wasn't called "the Doctor", but "Dr. Who".
Yet at a basic level, the comics were hampered by the inclusion of two children as his companions.
Though they may well have made it easier for kids — the primary target audience for the comic strips — to relate to the Doctor, they made it almost impossible for a well-rounded portrayal of the First Doctor's many qualities.
Especially profound was the loss of the Doctor's inherent "grumpiness"; with no adults around, the Doctor had no target for his anger.
Thus, the comic First Doctor was reduced to being just a grandfather with a time-space ship.
However, even these two points were somewhat in doubt.
The comic TARDIS wasn't actually much of a time-travel device.
As almost every story was set in the far future, it was little more than a simple spaceship.
That threw the First Doctor's inclination towards historical adventures out the window.
In addition, his status as "grandfather" was a point of incredulity, as well.
How could he be the grandfather to John and Gillian?
What was their relationship to the never-referenced Susan?
How did the stories told in the comic strips relate to the television series?
These were all questions left completely unanswered.
Worse still, the comic First Doctor was deprived even of the Daleks.
Since Terry Nation had licensed the comic Daleks to appear only by themselves from 1965 to 1967, the comic First Doctor never encountered them.
He was forced instead to repeatedly face the TV Comic "substitute", the Trods.
The best the TV Comic First Doctor could muster by way of resembling himself was a lone story that tied in with an atypical television adventure: Dr. Who and the Zarbi on the Web Planet.
It really wasn't until Doctor Who Magazine began publishing a handful of original First Doctor stories that the William Hartnell portrayal was really seen in comics.
Consequently, most of the First Doctor's companions didn't have their comic debuts until the early 1990s.
By then, thirty years after the fact, it was really a case of "too little, too late".
Comic readers are still waiting for the First Doctor to encounter the Daleks.
Given these facts, it is perhaps not surprising that, as a matter of Doctor Who Magazine continuity, the entirety of the First Doctor's TV Comic run was retconned out of existence as a dream of the Eighth 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, having held the role for seven seasons. 
"Lungbarrow" wrapped up the last of the continuity of the New Adventures and put the Doctor on course to gather the Master's remains from Skaro, as depicted in the 1996 Doctor Who television movie.
It is also one of a number of the New Adventures which is hard to obtain and is often seen on auction websites such as eBay at prices many times the original cover price.
The novel which followed "Lungbarrow", Lance Parkin's "The Dying Days", featured the Eighth Doctor.
When Virgin subsequently lost their licence to print original "Doctor Who" fiction, they chose to focus on a character from the New Adventures which the BBC did not own, former companion Bernice Summerfield.
"Lungbarrow" serves, in concert with "Dying Days", to gradually increase the standing of Summerfield's character, laying the groundwork for the later appearance of the Seventh Doctor's then-companion, Chris Cwej, in Summerfield's own novels.
Platt's novel, though, is largely concerned with concluding what was known as the "Cartmel Masterplan".
In the final two seasons of the original 1963-1989 run of "Doctor Who", the then script editor Andrew Cartmel introduced new elements of mystery into the character of the Doctor.
Suggestions of dark secrets that the Doctor might be more than just a Time Lord were inserted into scripts of stories such as Ben Aaronovitch's "Remembrance of the Daleks" and Kevin Clarke's "Silver Nemesis".
Had the series not been effectively cancelled in 1989, the following series would have made some of these revelations.
"Lungbarrow" began life as a television script, which was rejected by John Nathan Turner on the grounds that it revealed too much about the Doctor and the Time Lords, too quickly.
Elements of Platt's planned "Lungbarrow" instead became part of the Series 26 serial "Ghost Light", such as the sinister house keeper, the trapped investigating policeman and finale based around the family dinner.
If produced, the story would have featured Ace as the main companion and been set entirely within the House.
Along the way to this resolution, "Lungbarrow" ultimately reveals much new information about the Doctor's home world and race, some of which had been hinted at ever since the first New Adventures novel.
Many of the New Adventures authors migrated to the BBC Books "Doctor Who" line and elements of this backstory also made their way into subsequent novels.
However, there have also been elements in those novels that contradict it.
