A midway at a fair (commonly an American fair such as a county or state fair) is the location where carnival games, amusement rides, entertainment, dime stores, themed events, exhibitions and trade shows, pleasure gardens, water parks and food booths cluster.
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 amusement rides (among them the original Ferris Wheel), belly dancers, balloon rides, and other attractions.
After the Exposition, the term midway came into use 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.
