Key date

  • The widely accepted “release date” used by Disney and most historians is November 18, 1928 , and this date is also celebrated as Mickey Mouse’s official birthday.
  • Earlier that year, there were limited test screenings and sound tests, but the full public debut with synchronized sound is tied to that November 18 premiere.

Extra quick scoop

  • Steamboat Willie is one of the earliest cartoons with fully synchronized sound, which helped make Mickey Mouse an instant star in late 1928.
  • Because it was released in 1928, the short entered the public domain in the United States on January 1, 2024, though Disney still holds separate trademark rights in the character designs and logos.
