History of hula hoop
Although the exact origins of hula hoops are unknown, children around the world have played with hoops, twirling, rolling and throwing them throughout history. Traditional materials for hoops include grapevines and stiff grasses. Today, they are often made of plastic.

In 1957 the hula hoop was reinvented by Richard Knerr and Arthur "Spud" Medlin, founders of the Wham-O toy company. The idea came from an Australian who had visited California who told Knerr and Melin about children twirling bamboo hoops around the waist in gym class. The new Hula Hoops were made possible by Marlex, a recently invented durable plastic.
Knerr and Medlin were unable to patent their vastly profitable "re-invention", as it had been in use for thousands of years; making the device out of a new material did not meet patent requirements of originality. They were largely able, however, to protect their invention by trademarking "Hula hoop".
