Etymology of モブ


In Japanese, モブ (short for モブキャラクター) refers to a character who plays a minor
role in anime/manga/games -
[source](http://dic.nicovideo.jp/a/%E3%83%A2%E3%83%96%E3%82%AD%E3%83%A3%E3%83%A9%E3%82%AF%E3%82%BF%E3%83%BC).
The same source claims that the etymology is 和製英語 and traces its origin to
Japanese animators in the 1970's.

In English, a "mob" refers to a type of non-player character in a computer
game. According to this
[source](http://en.wikipedia.org/wiki/Mob_%28video_gaming%29#cite_note-bartle-
origin-2) the term was invented by Richard Bartle as an abbreviation of
"mobile object". I can't find a date for it, but Bartle was born in 1960, so I
assume the term was coined some number of years after his birth.

The two words have very similar meanings in both languages but apparently two
completely different etymologies. Is anyone able to come up with additional
sources that confirm the different etymologies or sources that can refute one
of the two proposed etymologies?




If you look closely, you will see that the article tells you that "モブ" indeed
comes from the English word "mob". But this word had the sense of a
[crowd](http://en.wikipedia.org/wiki/Mob) long before it had the sense of a
NPC in a video game. In this sense, the "モブ" characters were the ones that
were drawn in a crowd, for example in sports scenes (cf. second paragraph)
from which the main character would stand out.

The sense of a NPC came later, and is indeed appropriate for animation but I
think we are looking at a coincidence:

  * In Japanese the "crowd of characters" became a "featureless character"
  * For the NPC, their acronym became their name and is the same as the actual word used to describe a crowd.

However please note that the etymology of "mob" is "mobile vulgus" in latin,
it is thus no coincidence that a "mobile object" would be abbreviated in the
same way and land on the same word, "mob".

Cheers !
