Hill Company in Chicago on May 17, 1900,[nb 1] it has since been reprinted numerous times, most often under the name The Wizard of Oz, which is the name of both the 1902 stage play and the extremely popular, highly acclaimed 1939 film version. The story chronicles the adventures of a girl named Dorothy in the Land of Oz. Thanks in part to the 1939 MGM movie, it is one of the best-known stories in American popular culture and has been widely translated.
