Eighty-six years ago today, Mickey Mouse and Minnie Mouse made their official debut in "Steamboat Willie," the 1928 animated short that helped to launch an entertainment empire (their actual first appearance was in a May 1928 test screening of "Plane Crazy").

To celebrate the occasion, Biography has released a history of Mickey Mouse (sorry, Minnie), highlighting the iconic character's origins, his 1935 makeover, and his promotional role during World War II.

Disney, meanwhile, sent a rickshaw-driving Mickey on a trip across India for his birthday in a new animated short called "Mickey Mumbai Madness," which debuted today on Disney Channel India (you can watch it below, along with "Steamboat Willie").
