Why is Chicago called the “Windy City”?

Most people believe that Chicago got its nickname from its prevailing
winds, but that isn’t the case. In 1893, Chicago hosted the World’s
Columbian Exposition, celebrating the four hundredth anniversary of
America’s discovery. The city’s aggressive promotional campaign for
the event offended the people of New York, whose press nicknamed it
the Windy City to mock its bragging ways. The moniker stuck, but, for-
tunately for Chicago, its original meaning has been forgotten by most.
