The term originated from the World's Columbian Exposition held in Chicago, Illinois, in 1893. It was the first world's fair with an area for amusements which was strictly separated from the exhibition halls. This area, which was concentrated on the city's Midway Plaisance, included carnival rides, among them the first Ferris wheel, belly dancers, balloon rides, and other attractions.
After the Exposition, the term midway came to be used as a common noun in the United States and Canada to refer to the area for amusements at a county or state fair, circus, festival, or amusement park.
