How did abridged versions of anime get started? I was watching anime clips on YouTube and I stumbled upon an abridged version of an anime. The process of dubbing an anime using the same scenes but with a different voice and script, they were changing the dialogues of characters to make it funny.

This is an example video

It was Gundam Wing (Entitled "Gundam Abridged-ning") 

So how did this kind of voice dubbing and making it more funny get started?
LittleKuriboh's Yu-Gi-Oh! Abridged is often cited as being the first abridged series and the one to start inspiring others in a chain reaction like manner. (The latest episode even makes fun of this fact.)

The linked wiki page mentions that he originaly


  ... was inspired variously by the editing process of The Blair Witch Project, and Reduced Shakespeare Company's The Complete Works of Shakespeare (Abridged).


The series is notable in that it was for a long time voice acted and edited by a single person.
