Yo-Yo: It's a toy; it's a sport; it's a verb. It's been a toy for centuries, known by many names throughout its history, including bandalore, quiz, twirler, whirl-a-gig, and other names in different cultures.

The yo-yo was commercialized in America in the 1920s by Pedro Flores, a Filipino immigrant who produced the first Yo-Yo by that name in California. Not only did Flores import the idea from his native Phillipines, but also the name for it; "Yo-Yo" meant something like "come come" or "come back" in the native Tagalog language.

If Pedro Flores is credited with naming the Yo-Yo, it is D.F. Duncan Sr., who is recognized for successfully building the brand. Duncan bought the business from Flores and first trademarked Yo-Yo in the United States in 1929. So successful was Duncan's marketing, the public adopted the term "yo-yo" and rival companies challenged Duncan's trademark. In 1965, the Federal Court of Appeals ruled that the term had become generic, and so could be used by anyone. Then, everyone got into the game.

Duncan successfully marketed and manufactured yo-yos for many decades from his hometown, Luck, Wisconsin. But, as luck would have it, the Duncan company went bankrupt during the yo-yo heyday of the 1960s. The Duncan brand was acquired by Flambeau, and is still a leading name in yo-yoing.

Now, in the 75th Anniversary year since Duncan trademarked the name for Flores's toy, the yo-yo craze is coming back. In addition to technological advances, the Internet is helping a new generation learn how to yo-yo and share yo-yo knowledge and skills over websites like the yoyoing blog.
