Tetherball, or Do-Do

The film 'Tetherball, or Do-Do' was produced by the American Mutoscope & Biograph company. While several sources and the user hint at a 1900 date, the Library of Congress and the American Film Institute (AFI) Catalog record the official copyright registration and release of this specific title as August 20, 1904 (registration H49733). Regardless of the variance between 1900 and 1904, the work was published well before the definitive cutoff of January 1, 1928. Under the Copyright Term Extension Act, all works published in the United States prior to 1928 have entered the public domain due to the expiration of their maximum 95-year copyright term. No renewal or registration status beyond this date can extend its protection in the US.
