A toy is something to play with, for children, adults or both. They may either be the sole device used in an enjoyable activity or one of many. Toys have been in existence for thousands of years; dolls either of infants, animals, or soldiers, and miniature representations of the tools of adults are readily found at archaeological sites. The Inca, for example, had a rolling toy even though their adult culture did not employ the wheel. Two comparatively recent developments of toys have been their mass production and copyrighting. A number of these copyrighted, mass-produced toys are associated with particular decades in the twentieth century.
