The
Bureau International des Expositions (BIE)
was founded in 1928 and sanctions international
expositions as well as other exhibitions.
Not all events that most people would categorize
as a world's fair has been sanctioned by the
BIE, most notably the 1964-'65
New York World's Fair.
In coming years, the BIE will decide who will host Expo 2015 as well as the smaller Expo 2012 or Expo 2013.
