"Frisbee" (TM) is the trade name for a round plastic flying disc toy, made by the Wham-O company. Wham-O also also makes the Hula Hoop, the Slip'n'Slide, the original Super Ball, and the Hacky Sack.
Inspired by kids playing catch with metal pie tins, Walter Frederick Morrison and Warren Franscioni invented a plastic version in 1948. Morrison sold the rights to Wham-O, who began selling the "Pluto Platter" in 1957. The name was changed to Frisbee in 1958.
Since the birth of the Frisbee, a number of Frisbee sporting events have evolved. They include Ultimate Frisbee, Frisbee Golf, and Frisbee Freestyle. Frisbee sports are inexpensive, needing little beyond the disc itself, which costs around $10.
The World Flying Disc Federation (WFDF) is responsible for hosting World Championships and developing Rules of the Game for Ultimate Frisbee, Disc Golf, Freestyle, and other flying disc sports. In 2004, despite Frisbee's reputation for being a "hippie sport", the WFDF signed the World Anti-Doping Agency Code, subjecting Frisbee players to the same anti-doping standards as many other athletes. Alcohol consumption, however, is still allowed.
