Mickey Mouse first appeared in the short film "Steamboat Willie" in 1928, marking the beginning of Disney's legacy in animation. This iconic character was created by Walt Disney and Ub Iwerks and quickly became a symbol of the Disney brand. Interestingly, Mickey was originally going to be named "Mortimer Mouse," but Disney's wife, Lillian, felt that the name sounded too pompous and suggested "Mickey" instead. Over the years, Mickey has become one of the most recognizable and beloved characters in the world, appearing in countless films, TV shows, and merchandise. His cheerful personality and adventurous spirit continue to capture the hearts of both children and adults.
