What it is

Pedro Flores opened the first yo-yo factory in Santa Barbara in 1928 and popularised the toy with demonstrations. Around 1929-1932 the businessman Donald Duncan bought his company and the brand and turned it into a mass craze.

The toy is much older (Greek yo-yo discs c. 500 BC, the 18th-century bandalore). The story that Flores copied a Philippine hunting weapon is an unproven legend. The name 'yo-yo' is sometimes attributed to Ilocano or Tagalog, also without proof.

What it led to

  • the yo-yo craze of the 1930s (Duncan)
  • competition contests and tricks
  • modern bearing-based yo-yos (sleeper and ball-bearing)
