The yo-yo is a toy consisting of two equally sized and weighted discs of plastic, wood, or metal, connected with an axle, around which string is wound. First becoming popular in the 1920s, "yo-yoing" still enjoys a following of children as well as adults.
The yo-yo is usually credited as having been invented in the Philippines centuries ago. The name yo-yo may have been derived from the Filipino word tayoyo which means to spin. The term was first published in a dictionary of Filipino words printed in 1860.
The first United States patent on the toy was issued to James L. Haven and Charles Hettrich in 1866 under the name whirligig, however, the yo-yo would remain in relative anonymity until 1928 when a Filipino American named Pedro Flores opened the Yo-Yo Manufacturing Company in Santa Barbara, California. The business started with a dozen handmade toys; by November of 1929, Flores was operating two additional factories in Los Angeles and Hollywood, which altogether produced 300,000 units daily.
A yo-yo competition normally consists of two parts, a set of compulsory tricks and a freestyle, where points are scored for each and the winner is the Yo-yoer who scores the most points. Compulsory tricks ( also known as a Trick Ladder ) are a set of tricks that have been chosen before the contest, and the competitor must successfully complete each trick on their first or second attempt to score points. The freestyle is when the yoist performs a routine to their choice of music in front of a panel of judges, and is judged based on difficulty of the tricks, synchronization with the music and artistic performance.
The TV Times world Yo-Yo championship was held in the United Kingdom in 1974 with heats across the United Kingdom and a final in London in 1975, the championship was sponsored by the Louis Marx toy company with the 'Lumar' Brand of Yo-Yo. The competition was judged by a celebrity panel in each city and also Lumar demonstrator and European Yo-Yo champion Don Robertson. The winner of the final was Simon Harris (intermediate category). The championship was not repeated.
