Setting the scene
Wham-O founders Richard Knerr and Arthur Melin had imported Australian bamboo exercise hoops; after tweaking Marlex plastic tubing, they trademarked 'Hula Hoop' and launched a marketing blitz tying the toy to rock-and-roll youth culture.
What happened
The hula hoop fad peaked in 1958 when an estimated twenty-five million hoops sold in four months, with Wham-O shipping 50,000 units daily at the craze's height.
Why it still matters
Schools banned hoops when chains of kids linked up in playgrounds, fearing disruption; though sales collapsed by 1959, the hoop survived as fitness fad and symbol of postwar disposable toy booms driven by television advertising.
