One of the biggest fads of all time is the hula-hoop, invented in 1957, by an Australian. The name "hula hoop" came from the Hawaiian dance its users seemed to imitate. The invention was licensed to Wham-O, who sold 25 million hula-hoops in two months. Almost 100 million international orders followed. They were manufacturing 20,000 hoops a day at the peak of popularity.
