Yale University students appear to have begun the Frisbee in the 1920s, when they threw around metal pie tins from the Frisbie Bakery of Bridgeport, Connecticut.
Middlebury College in Vermont has also taken credit for inventing the game.
As a commercial venture, however, Frisbee began with a saucer-shaped toy invented by Walter Frederick Morrison in the 1950s.
The Wham-O company of California introduced it in 1957 as the Pluto Platter; the name was changed to Frisbee in 1959.
