Google won't give me the answer. Maybe one of you people can find the answer on some obscure 90's search engine or something.

it's Missingno. not MissingNo watch your grammar.
That's a very trivial thing
it's got nothing to do with grammar

Also obviously no one knows WHO discovered missingno, as several people would have, and it would eventually spread out in news.
It was discovered around 1999....

This question is pretty much unanswerable and pointless, I mean  it would have been discovered multiple times by different people.
If this is such a bad question, how is it getting votes? It was even tagged unanswerable by the user who asked it.
Because apparently hard question = lotsa votes :|
Yep, grime x3 like mommy always says, the harder the better!
it's getting vote because it's difficult to answer and frankly would be quite interetsing to know the answer to... that's why all questions are upvoted

The Missingno species was first discovered by Nintendo in the original title “Pokémon Red Version and Blue Version,” which was published in the May 1999 issue of Nintendo Power. Describing the phenomenon as a “programming quirk,” Nintendo warned the gamers against encountering it, claiming the game may have to be reset completely in order to remove the graphical errors. Since becoming a well-known trivia among Pokémon gamers in 1999, there has been extensive discussions about encountering MissingNo on purpose, which involves trigger three in-game events to summon the glitch.

How did Nintendo get access to the code of the game and how they spotted an error on the code?
Since Nintendo publishes Pokemon, why wouldn't they be able to look at the game's code? Considering how poorly made Pokemon Red and Blue were compared to other Nintendo games, the error in the game's code would probably be fairly easy to spot.
