Donald Duncan did not make the first yo-yo company-he bought it.
Pedro Flores founded a yo-yo company in 1928 in Santa Barbra, CA entitled “The Yo-yo Manufacturing Company” (Crazy, right?) Which consisted of mass-producing handmade toys.
In 1929, Donald Duncan saw this as a great way to make money and bought the company. He renamed “Duncan Toys” and made the Duncan O-Boy, the first Duncan yo-yo.
When the 1069’s came, Duncan realized that his post-WWII sales were unsatisfactory, he eventually came up with the Butterfly and started using commercials to advertise. He was very successful.
However, the same decade Duncan tried to trademark the work “yo-yo” and was sued in a court case based on a saying that “yo-yo” was a term in “common speech”, Duncan was losing money.
He eventually sold the company to Flambeau Plastics who owns it to this date.
I’m not saying Duncan was not a revolutionary, but I am saying that they were not the first yo-yo company.
