In 1957, Joan Anderson brought back a bamboo "exercise hoop" from Australia, and came up with the name Hula Hoop® at a dinner party. Her husband showed it to Arthur "Spud" Melin and they agreed on a gentleman's handshake that they would share in any profits. Wham-O originally manufactured 42 in (1.1 m) diameter hoops from Marlex plastic. With giveaways, national marketing and retailing, a fad begin in July of 1958, and 25M plastic hoops were sold in less than four months! Sales reached more than 100M units in two years.
