The Walt Disney Company, commonly referred to as simply Disney, is an American multinational mass media and entertainment conglomerate headquartered at the Walt Disney Studios in Burbank, California. Disney was founded on October 16, 1923 as an animation studio, by brothers Walt Disney and Roy Oliver Disney as Disney Brothers Cartoon Studio; it also operated under the names Walt Disney Studio and Walt Disney Productions before changing it to 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. After becoming a major success by the early 1940s, Disney diversified into live-action films, television, and theme parks in the 1950s. However, following Walt Disney's death in 1966, the company's profits, especially in the animation division, began to decline. Wikipedia
