A frisbee (pronounced FRIZ-bee, origin of the term dates to 1957, also called a flying disc or simply a disc) is a gliding toy or sporting item that is generally made of injection molded plastic and roughly 8 to 10 inches (20 to 25 cm) in diameter with a pronounced lip. It is used recreationally and competitively for throwing and catching, as in flying disc games. The shape of the disc is an airfoil in cross-section which allows it to fly by generating lift as it moves through the air. Spinning the disc imparts a stabilizing gyroscopic force, allowing it to be both aimed with accuracy and thrown for distance.
A wide range is available of flying disc variants. Those for disc golf are usually smaller but denser and tailored for particular flight profiles to increase or decrease stability and distance. The longest recorded disc throw is by David Wiggins Jr. with a distance of 1,109 feet (338 m).  Disc dog sports use relatively slow-flying discs made of more pliable material to better resist a dog's bite and prevent injury to the dog. Flying rings are also available which typically travel significantly farther than any traditional flying disc. Illuminated discs are made of phosphorescent plastic or contain chemiluminescent fluid or battery-powered LEDs for play after dark. Others whistle when they reach a certain velocity in flight.
The term frisbee is often used generically to describe all flying discs, but Frisbee is a registered trademark of the Wham-O toy company. This protection results in organized sports such as Ultimate or disc golf having to forgo use of the word "Frisbee".  
Walter Frederick Morrison and his future wife Lucile had fun tossing a popcorn can lid after a Thanksgiving Day dinner in 1937. They soon discovered a market for a light duty flying disc when they were offered 25 cents for a cake pan that they were tossing back and forth on a beach near Los Angeles, California.  "That got the wheels turning, because you could buy a cake pan for five cents, and if people on the beach were willing to pay a quarter for it, well—there was a business," Morrison told The Virginian-Pilot newspaper in 2007. 
The Morrisons continued their business until World War II, when he served in the Army Air Force flying P-47s, and then was a prisoner of war.  After the war, Morrison sketched a design for an aerodynamically improved flying disc that he called the Whirlo-Way,  after the famous racehorse. He and business partner Warren Franscioni began producing the first plastic discs by 1948, after design modifications and experimentation with several prototypes. They renamed them the Flyin-Saucer in the wake of reported unidentified flying object sightings. 
"We worked fairs, demonstrating it," Morrison told the Virginian-Pilot. The two of them once overheard someone saying that the pair were using wires to make the discs hover,  so they developed a sales pitch: "The Flyin-Saucer is free, but the invisible wire is $1."  "That's where we learned we could sell these things," he said, because people were enthusiastic about them. 
Morrison and Franscioni ended their partnership in early 1950,  and Morrison formed his own company in 1954 called American Trends to buy and sell Flyin-Saucers, which were being made of a flexible polypropylene plastic by Southern California Plastics, the original molder.  He discovered that he could produce his own disc more cheaply, and he designed a new model in 1955 called the Pluto Platter, the archetype of all modern flying discs. He sold the rights to Wham-O on January 23, 1957.  [a] In 1958, Morrison was awarded U.S. Design Patent D183,626 for his product.
In June 1957, Wham-O co-founders Richard Knerr and Arthur "Spud" Melin gave the disc the brand name "Frisbee" after learning that college students were calling the Pluto Platter by that term,  which was derived from the Connecticut-based pie manufacturer Frisbie Pie Company,  a supplier of pies to Yale University, where students had started a campus craze tossing empty pie tins stamped with the company's logo—the way that Morrison and his wife had in 1937. 
The man behind the Frisbee's success, however, was the Southern Californian Ed Headrick, hired in 1964 as Wham-O's general manager and vice president of marketing. Headrick redesigned the Pluto Platter by reworking the mold, mainly to remove the names of the planets, but fortuitously increasing the rim thickness and mass in the process, creating a more controllable disc that could be thrown more accurately. 
Wham-O changed their marketing strategy to promote Frisbee use as a new sport, and sales increased. In 1964, the first professional model went on sale. Headrick patented its design; it featured raised ridges (the "Rings of Headrick") that were claimed to stabilize flight. 
Headrick became known as the father of Frisbee sports;  he founded the International Frisbee Association and appointed Dan Roddick as its head. Roddick began establishing North American Series (NAS) tournament standards for various Frisbee sports, such as Freestyle, Guts (flying disc game), Double Disc Court, and overall events.  Headrick later helped to develop the sport of disc golf, which was first played with Frisbees and later with more aerodynamic beveled-rim discs, by inventing standardized targets called "pole holes."   When Headrick died, he was cremated, and his ashes were molded into memorial discs and given to family and close friends[ citation needed] and sold to benefit The Ed Headrick Memorial Museum. 
The IFT guts competitions in Northern Michigan, the Canadian Open Frisbee Championships (1972), Toronto, ON, the Vancouver Open Frisbee Championships (1974), Vancouver, BC, the Octad (1974), New Jersey, the American Flying Disc Open (1974), Rochester, NY and the World Frisbee Championships (1974), Pasadena, CA are the earliest Frisbee competitions that presented the Frisbee as a new disc sport. Before these tournaments, the Frisbee was considered a toy and used for recreation. 
Double disc court was invented and introduced in 1974 by Jim Palmeri,  a sport played with two flying discs and two teams of two players. Each team defends its court and tries to land a flying disc in the opposing court.
Dogs and their human flying disc throwers compete in events such as distance catching and somewhat choreographed freestyle catching. 
This is a precision and accuracy sport in which individual players throw a flying disc at a target pole hole. In 1926, In Bladworth, Saskatchewan, Canada, Ronald Gibson and a group of his Bladworth Elementary school chums played a game using metal lids, they called "Tin Lid Golf." In 1976, the game of disc golf was standardized with targets called "pole holes" invented and developed by Wham-O's Ed Headrick. 
In 1974, freestyle competition was created and introduced by Ken Westerfield and Discraft's Jim Kenner. Teams of two or three players are judged as they perform a routine that consists of a series of creative throwing and catching techniques set to music. 
A half-court disc game derived from Ultimate, similar to hot box. The object is to advance the disc on the field of play by passing, and score points by throwing the flying disc to a teammate in a small scoring area. 
The game of guts was invented by the Healy Brothers in the 1950s and developed at the International Frisbee Tournament (IFT) in Eagle Harbor, Michigan. Two teams of one to five team members stand in parallel lines facing each other across a court and throw flying discs at members of the opposing team. 
A patented game scoring points by throwing and deflecting the flying disc and hitting or entering the goal. The game ends when a team scores exactly 21 points or "chogs" the disc for an instant win. 
The most widely played disc game began in the late 1960s with Joel Silver and Jared Kass. In the 1970s it developed as an organized sport with the creation of the Ultimate Players Association by Dan Roddick, Tom Kennedy and Irv Kalb.  The object of the game is to advance the disc and score points by eventually passing the disc to a team member in the opposing team's end zone. Players may not run while holding the disc.
