Dickson Experimental Sound Film

The 'Dickson Experimental Sound Film' (also known as 'The Dickson Violin'), produced by William Kennedy Dickson for the Edison Manufacturing Company, is definitively in the public domain in the United States. Under current US copyright law, all works published or registered before January 1, 1928, have seen their copyright terms expire and have entered the public domain. While the film was produced as a technical test for the Edison Kinetophone system in late 1894 or early 1895, its age places it well beyond any possible term of protection. Even if copyright had been properly registered and renewed under the laws of the time, the maximum possible duration for a work from 1894 ended decades ago. The film is widely recognized as the first known instance of a motion picture with live-recorded sound. The film's status is cited in numerous databases of early cinema history, including the Library of Congress (which holds a reconstructed version) and the Internet Archive. As a pre-1928 American production, there are no legal grounds for continued copyright protection.
