The Walt Disney Company, commonly and globally known as simply Disney, is an American multinational mass media and entertainment conglomerate headquartered at the Walt Disney Studios complex in Burbank, California. Founded on October 16, 1923, as an animation studio by brothers Walt Disney and Roy Oliver Disney as Disney Brothers Cartoon Studio, Disney operated under the names Walt Disney Studio and Walt Disney Productions before adopting its current name in 1986. In 1928, Disney established itself as a leader in the animation industry with the short film Steamboat Willie. The film used synchronized sound to become the first post-produced sound cartoon, and popularized Mickey Mouse, who became Disney's mascot and corporate icon.
