I saw over the internet that Accel World came out sometime in 2009 and Sword Art Online came out around in 2013, but it seems like many people saying SAO came first than Accel World.

Which came first, Accel World or Sword Art Online?

Accel World came first. According to their Wikipedia pages, Accel World light novel started in February 2009 while Sword Art Online started in April 2009. If you are referring to anime release, then the same can also be said since Accel World anime started airing in April 2012 while SAO anime started airing in July 2012.

As pointed out by @Memor-X, some people say that SAO came first but this most likely refers to the chronology of the events in both stories and not to the release order of light novels/anime because as mentioned here, the events in SAO happened before the events in Accel World on the same universe/timeline.

  • to answer why the OP is seeing people say SAO came first we have an answer that probably explains why they are seeing that

  • Oh okay. The question, however, should have mentioned this fact as it is phrased in a way that it seems like it is only asking for the release order of the light novels/anime, not the chronology of the events in the two light novels/anime. I'll edit my answer to include this info. Thanks :)

    i think maybe the OP might not know, the question does say "but it seems like many people saying SAO came first than accel world." and story chronological order is the only way that explains why they would think that

  • You have the anime and light novel dates. Unfortunately you missed the fact SAO had a much earlier Web Novel.

  • @TUSF A lot was changed from the web novels and light novels. If you look up the wiki, you can see the differences with each volume that were released as a web novel. From what I understand, the 'anime story' is based on the light novels (which is what the OP was referring to) and since there were changes (for me, there were a lot of changes) from the web novel, I don't think the anime story in SAO's adaptation was based on the original web novel release.

Sword Art Online was first. Kawahara originally wrote SAO in 2001 for a Dengeki Light novel contest, but due to exceeding the contest's page limit, he posted it online in 2002 under the pseudonym "Kunori Fumio". The story eventually concluded (with the Alicization arc) in 2008.

Afterwards, he decided to re-enter the same contest with what would later be called Accel World. His editor (Miki Kazuma) found out about SAO and decided to get that published as well.
