Two friends, a garage and a sound effect.

Wham-O began with a hobby rather than a toy. The Guardian’s obituary of Arthur “Spud” Melin, published in July 2002, says that he and Richard Knerr had been students at the University of Southern California and bred falcons, training them by lobbing meatballs into the air with a homemade slingshot. They found that people were more interested in the slingshot than in the birds. The Los Angeles Times, in its January 2008 obituary of Knerr, says the boyhood friends started the company in 1948 in Pasadena, made slingshots with a band saw in the garage of Knerr’s parents, and named the business Wham-O for the sound the slingshot made when it hit its target.

That origin explains a name that still reads like a comic-book sound effect. The Guardian adds that Melin cut the slingshots and Knerr sanded them, and that the pair sold them in person at first, then by mail order and through dealers across the United States. The same Los Angeles Times account says the pair also sold boomerangs and crossbows in those early years before moving the company into a building in San Gabriel, California. A 2015 tribute by the Chicago Toy & Game Group (CHITAG) describes the founders as having “an open door for outside inventor ideas”, and that openness shaped the products the name is now attached to.

Ownership has changed hands several times since the founders stepped away. The Los Angeles Times reports that Knerr and Melin sold the company to Kransco Group in 1982, that Mattel bought it in 1994, and that Mattel sold it on to a group of investors in 1997. The San Francisco Chronicle reported in March 2010 that in 2006 Wham-O was bought by a Hong Kong company, and that Kyle Aguilar had bought it in the summer of 2009 with a group of private investors and become chief executive.

A hoop, a disc and a run of playful names.

The two products most closely tied to the brand both arrived as outside ideas. According to the Los Angeles Times, a friend told Knerr and Melin about a bamboo ring used for exercise in Australia, and they built their own plastic version. The paper says they tested it in 1958 at a Pasadena elementary school, telling children they could keep the hoops if they mastered them, and then gave hoops away in neighbourhoods to get people talking. CHITAG dates the launch of the Hula Hoop to January 1958 and also describes the free samples handed to schoolchildren.

The flying disc came from inventor Fred Morrison. The Guardian obituary says Morrison demonstrated his plastic platter to Wham-O, that the company first sold it under another name, and that in 1958 it was renamed the Frisbee. The paper gives two explanations for the name: a phonetic spelling of what Knerr heard students calling it on a college tour, or a nod to a comic-strip character called Mr Frisbie. The same obituary notes that the Frisbee had its own plant in San Gabriel.

Many of the later names follow the same pattern of a short, spoken-sounding word. The Los Angeles Times lists the Superball, Slip ’N Slide, its garden-hose cousin the Water Wiggle, and Silly String among the toys that followed, and CHITAG’s 2015 tribute names Frisbee, Slip-N-Slide, Boogie Board, Hacky Sack, Hula Hoop and Super Ball as the classic lines the company was still marketing at the time. In 2008, CHITAG notes, Chronicle Books published a history of the company, the WHAM-O Super-Book by Tim Walsh.

Design and documentation.

Outdoor play and ride-on toys sit in a part of the toy trade where the product is meant to leave the house: things that are thrown, flown, launched, pushed, pedalled or ridden in gardens, parks, driveways and beaches. Many of the names in this field began with a single object and built a brand around it, while others grew into wider ranges of moulded, sewn or wooden goods sold through toy shops, garden centres and general retailers.

Because these toys are used outdoors and seen from a distance, their identities tend to lean on bright, saturated colour and simple, bold names that read on a box, a deck or a canopy. Behind the names, ownership can change over time, and design, sales and manufacturing are often in different places, so the country on the box and the country of production may not be the same.

Each guide separates what independent, dated sources record from what the company says about itself — who started it, who owns it now, where its products are made and how its look has developed — and marks plainly what rests only on the company’s own word.

From Pasadena to Emeryville to Carson.

The 2010 San Francisco Chronicle report gives a snapshot of the company after the Aguilar purchase. It placed Wham-O’s headquarters in Emeryville, California, and said Aguilar also owned and ran Manufacturing Marvel Inc., which made toys and promotional products at factories in the United States, China and Mexico. The paper reported that Marvel was already making some Wham-O products overseas and that the plan was to bring some Wham-O manufacturing back to Marvel plants in Lompoc, California, and in Michigan. In February 2010, the same report said, Wham-O bought Sprig Toys, a small Colorado company whose “Sprigwood” material was to be used in a range of preschool toys.

The company today presents itself from Southern California. Its own website, read in October 2026, lists the United States office as Intersport Corp., doing business as Wham-O, in Carson, California, alongside separate contacts for Japan and for Wham-O Australia. The same site groups its products under trademarked names including Frisbee, Hula Hoop, Slip ’N Slide, Boogie Board, Hacky Sack and Superball.

For a design guide, Wham-O shows how far a name can travel when it is short, loud and attached to a simple object: a slingshot noise turned into a company that put its mark on a disc, a hoop and a water slide and kept it through several owners. Compare the backyard launcher in our Stomp Rocket brand guidelines and the Chicago wagon maker in our Radio Flyer brand guidelines. For this guide we use slingshot red, hoop yellow and disc sky with a heavy display sans, an unofficial interpretation; no product or logo is reproduced.
