The yo-yo has a long history, with its origins dating back to at least 500 BC in ancient Greece, where it was used as a toy. However, the modern version of the yo-yo was popularized in the United States in the 1920s when it was patented by Donald F. Duncan. The toy has since evolved and remains popular worldwide, with various designs and competitions.
