Beaucoup de manifestations US ont une appellation qui se
termine par c-o-n, Game-Con, Video-Con etc.
À quoi cela correspond-il, conference, congress, convention ?

Convention. Tiens, il y a même une entrée dans le Jargon file :

:con: [from SF fandom] /n./  A science-fiction convention.  Not
   used of other sorts of conventions, such as professional meetings.
   This term, unlike many others of SF-fan slang, is widely recognized
   even by hackers who aren't {fan}s. "We'd been corresponding on
   the net for months, then we met face-to-face at a con."
