Yomega was founded in 1983, and had quickly made a mark on the yo-yo industry with their 1984 release of the Yo-yo with a Brain. The original Brain was based upon Michael Caffrey's U.S. mechanical patent #4,332,102, which was invented in 1980 and that patent was issued on June 1st, 1982. At the turn of the century, 1999-2000, Yomega partnered with McDonald's and distributed a large number of Yomega X-Brain and Firestorm yo-yos at restaurant locations throughout the U.S.
