What is the name of the cartoon that introduced Mickey Mouse to the world?

The cartoon that introduced Mickey Mouse to the world was Steamboat Willie. Released in 1928, the short became Mickey’s public debut and transformed the character into an international star.

Walt Disney and Ub Iwerks created the film, which features Mickey working aboard a river steamboat under the command of Pete. Minnie Mouse also appears, making the short an early landmark for both characters. Its synchronized soundtrack, including whistles, musical effects and rhythmic action, made a powerful impression on contemporary audiences.

There is an important technical and historical distinction. Mickey had already appeared in test screenings of Plane Crazy and The Gallopin’ Gaucho, and both films were produced before Steamboat Willie. However, those earlier shorts initially failed to secure distribution. Steamboat Willie was the first Mickey film released to the public, so it is conventionally called his debut.

The short premiered in New York on November 18, 1928. It is often described as the first sound cartoon, but earlier sound cartoons existed; its real achievement was using synchronized sound so effectively that it helped define Mickey’s screen identity.
