In 1929, just two years after The Jazz Singer introduced synchronized sound to theaters nationwide, The Broadway Melody was released as a full-length movie musical with synchronized sound nearly throughout. One sequence was even in Technicolor.

The movie won the first best-picture Oscar awarded to a sound film. Despite its fame and technical innovation, we won’t see it in its full glory when it joins the public domain in 55 days: the Technicolor version is now lost. #PublicDomainDayCountdown
