A Brief History of World's Fairs

New York City, 1939: The World of Tomorrow
The 1939-40 New York World's Fair, held at Flushing Meadows–Corona Park in New York City, signified a shift from the fair's traditional role of featuring technological advancements to that of a cultural exchange between nations. The Big Apple adopted the slogan "Dawn of a New Day" for its first fair, its purpose being to show visitors "the world of tomorrow." At the center of the fair were two Modernist structures known as the Trylon and the Perisphere. The Trylon consisted of a 700-ft. (210 m) spire, while the Perisphere, pictured above, was a giant sphere 180 ft. (55 m) in diameter.
