In 1928, [[Pedro Flores (Yo-yo manufacture)|Pedro Flores]], a [[Filipino people|Filipino]] immigrant to the United States, opened the Yo-yo Manufacturing Company in [[Santa Barbara, California]].<ref name=flores>{{Citation

The principal distinction between the Filipino design popularized by Flores and the more traditional yo-yos is in the way the yo-yo is strung. In older (and some remaining inexpensive) yo-yo designs, the string is tied to the axle using a knot. With this technique, the yo-yo just goes back and forth; it returns easily, but it is impossible to make it sleep. In Flores's design, one continuous piece of string, double the desired length, is twisted around something to produce a loop at one end which is fitted around the axle. Also termed a ''looped slip-string'', this seemingly minor modification allows for a far greater variety and sophistication of motion, thanks to increased stability and suspension of movement during free spin.{{citation needed|date=October 2024}}

Shortly thereafter (c. 1929), entrepreneur [[Donald F. Duncan Sr.|Donald F. Duncan]] recognized the potential of this new fad and purchased the Flores yo-yo Corporation and all its assets, including the Flores name, which was transferred to the new company in 1932.{{citation needed|date=October 2024}}

In 1933, yo-yos were banned in [[Syria]], because many locals superstitiously blamed the use of them for a severe drought.<ref>{{cite news |author=<!--Staff writer(s); no by-line.--> |title= YO&ndash;YO BANNED IN SYRIA|url= https://trove.nla.gov.au/newspaper/article/48418581|work= Barrier Miner|location= Sydney, Australia|date= January 23, 1933|access-date= July 8, 2018}}</ref>

In 1946, the [[Duncan Toys Company]] opened a yo-yo factory in [[Luck, Wisconsin]]. The Duncan yo-yo was inducted into the [[National Toy Hall of Fame]] at [[The Strong]] in [[Rochester, New York]], in 1999.{{citation needed|date=October 2024}}
