Wham-O Inc. is an American toy company based in Carson, California, United States. It is known for creating and marketing many popular toys for nearly 70 years, including the Hula hoop, Frisbee, Slip 'N Slide, Super Ball, Trac-Ball, Silly String, Hacky sack, Wham-O Bird Ornithopter and Boogie Board,[1] many of which have become genericized trademarks.

Corporate history[edit]

Richard Knerr (1925–2008[2]) and Arthur "Spud" Melin (1924–2002[3]), two University of Southern California graduates who were friends since their teens, were unhappy with their jobs and decided to start their own business. In 1948 they formed the WHAM-O Manufacturing Company in the Knerr family garage in South Pasadena. Their first product was the Wham-O Slingshot, made of ash wood, which Knerr and Melin promoted by holding demonstrations of their own slingshot skills. The name "Wham-O" was inspired by the sound of the slingshot's shot hitting the target.[4] The powerful slingshot was adopted by clubs for competitive target shooting and small game hunting.[5] When they outgrew the garage, Knerr and Melin rented a building on S. Marengo Ave in Alhambra, California; and then, in 1955, moved their manufacturing plant to neighboring San Gabriel, California where they remained until 1987, when they sold the plant to Huy Fong Foods.

Products and marketing[edit]

A Frisbee made by Wham-O

In 1957, Wham-O, still a fledgling company, took the idea of Australian bamboo "exercise hoops", manufactured them in Marlex, and called their new product the Hula Hoop. (The name had been used since the 18th century, but until then was not registered as a trademark.) It became the biggest toy fad in modern history.[6][7] 25 million were sold in four months, and in two years sales reached more than 100 million.[8] "Hula Hoop mania" continued through the end of 1959, and netted Wham-O $45 million (equivalent to $452 million in 2024[9]).

Shortly thereafter, the company had another huge success with the Frisbee. In 1955 inventor Fred Morrison began marketing a plastic flying disc called the Pluto Platter. He sold the design to Wham-O in 1957. In 1959 Wham-O marketed a slightly modified version, which they had renamed the "Frisbee" two years earlier in 1957 – and once again a Wham-O toy became a common part of life through the 1960s.

In the early 1960s Wham-O created the Super Ball, a high-bouncing ball made of a hard elastomer Polybutadiene alloy, dubbed Zectron, with a 0.92 coefficient of restitution when bounced on hard surfaces. Around 20 million Super Balls were sold that decade, and the NFL named the Super Bowl games after it.[10]

The Frisbee and Hula Hoop created fads. With other products, Wham-O tried to capitalize on existing national trends. In the 1960s they produced a US$119 do-it-yourself bomb shelter cover. In 1962, they sold a limbo dance kit to take advantage of that fad; and in 1975, when the movie Jaws was released, they sold plastic shark teeth.

Many products were not successful. During an African safari in the early 1960s, Melin discovered a species of fish that laid eggs in the mud during Africa's dry season. When the rains came, the eggs hatched and fish emerged overnight. This inspired Melin to create the Instant Fish product, an aquarium kit consisting of some of the fish eggs, and some mud in which to hatch them.

Other products[edit]

Knerr and Melin marketed their products directly to children, including demonstrating their toys at playgrounds. They extensively researched new product ideas, including traveling around the world.[29] "If Spud and I had to say what we contributed," Knerr said, "it was fun. But I think this country gave us more than we gave it. It gave us the opportunity to do it."[30]

For many years, the company's strategy was to maintain eight to twelve simple, inexpensive products such as Frisbees, Super Balls, and Hula Hoops. New products were developed for tryout periods. Old ones were retired, for a few years or permanently, as their popularity waned. Since the toys were simple and inexpensive, they could be sold by a wide range of retailers, from large Department Stores to five and dime stores.

As Wham-O changed ownership, its new management adjusted this formula to accommodate the changing toy industry, which had increasingly complex toys and fewer distribution channels.

By 2006 Wham-O's product line included several groups of related items using licensed brand names. For example, Sea-Doo is a brand of personal water craft owned by Bombardier; Wham-O makes a Sea-Doo line of small inflatable rafts designed to be towed behind watercraft.

The company's lines are also more complex, and grouped in related categories—for example, the Sea-Doo line (about a dozen products), several Slip 'N Slide variations, and a group of "lawn games".

On January 31, 2011, Wham-O announced an agreement with ICM, the agency representing Atari video games, to represent Wham-O in movies, television, music, and online content based around its toys.[31]
