Star Trek Canon - TV Series

TV Series

As a rule, all Star Trek TV series that aired are considered canon, However, this policy does not make clear which version of the shows is the canon one. For example, the remastered TOS episodes released in 2006 present several visual differences from the episodes originally aired.

To further complicate matters, it has been noted that Gene Roddenberry was something of a revisionist when it came to canon. People who worked with Roddenberry remember that he used to handle canon not on a series-by-series basis nor an episode-by-episode basis, but point by point. If he changed his mind on something, or if a fact in one episode contradicted what he considered to be a more important fact in another episode, he had no problem declaring that specific point non-canon.

See, people can easily catch us, and say "well, wait a minute, in 'Balance of Terror', they knew that the Romulans had a cloaking device, and then in 'The Enterprise Incident', they don't know anything about cloaking devices, but they're gonna steal this one because it's obviously just been developed, so how the hell do you explain that?" We can't. There are some things we just can't explain, especially when it comes from the third season. So, yes, third season is canon up to the point of contradiction, or where it's just so bad... you know, we kind of cringe when people ask us, "well, what happened in 'Plato's Stepchildren', and 'And the Children Shall Lead', and 'Spock's Brain', and so on — it's like, please, he wasn't even producing it at that point. But, generally, the original series, not really the animated, the first movie to a certain extent, the rest of the films in certain aspects but not in all... I know that it's very difficult to understand. It literally is point by point. I sometimes do not know how he's going to answer a question when I go into his office, I really do not always know, and — and I know it better probably than anybody, what it is that Gene likes and doesn't like.— Richard Arnold, 1991 Another thing that makes canon a little confusing. Gene R. himself had a habit of decanonizing things. He didn't like the way the animated series turned out, so he proclaimed that it was not canon. He also didn't like a lot of the movies. So he didn't much consider them canon either. And – okay, I'm really going to scare you with this one – after he got TNG going, he... well... he sort of decided that some of The Original Series wasn't canon either. I had a discussion with him once, where I cited a couple things that were very clearly canon in The Original Series, and he told me he didn't think that way anymore, and that he now thought of TNG as canon wherever there was conflict between the two. He admitted it was revisionist thinking, but so be it.— Paula Block, 2005

Additionally, David Gerrold, in an interview about Star Trek: The Animated Series, commented on Roddenberry's parsimony and how it originally affected "canon":

Arguments about "canon" are silly. I always felt that Star Trek Animated was part of Star Trek because Gene Roddenberry accepted the paycheck for it and put his name on the credits. And DC Fontana -- and all the other writers involved -- busted their butts to make it the best Star Trek they could. But this whole business of "canon" really originated with Gene's errand boy. Gene liked giving people titles instead of raises, so the errand boy got named "archivist" and apparently it went to his head. Gene handed him the responsibility of answering all fan questions, silly or otherwise, and he apparently let that go to his head.

Another factor that contributes to blur the line between canon and non-canon is the fact that some writers like to include elements from popular non-canon or semi-canon works into canon episodes. Such is the case of the first names for Hikaru Sulu and Nyota Uhura, which were first used in the novel "The Entropy Effect" and the reference book "Star Trek II Biographies", respectively. Several concepts that first appeared in the Animated Series have also been used in other Star Trek productions, such as Kirk's middle name, first used in the episode "Bem" before it was used in Star Trek VI: The Undiscovered Country. The animated episode "Yesteryear" first introduced The Forge and the city of ShiKahr, which were later included in the Enterprise three-part story that started with "The Forge". However, despite the fact that elements borrowed from the Animated Series are considered canon, the status of the series itself remains in a gray, semi-canon area.

One final issue comes from text that appears on props such as computer displays, but is not legible during the episode, except in modern HDTV broadcasts. The transcript of the text can often be obtained through behind-the-scenes pictures and interviews. This leads to the question of whether material that is in the episodes but cannot be seen clearly should be considered canon. In many cases, this material tends to be inside jokes inserted by the production staff. Other kinds of information, such as the biographical information seen on a computer display in "In a Mirror, Darkly", has been stated to not be "hard canon".
