The Walt Disney Company (NYSE: DIS) (commonly referred to as Disney) is the largest media and entertainment conglomerate in the world in terms of revenue. Founded on October 16, 1923, by brothers Walt Disney and Roy Disney as the Disney Brothers Cartoon Studio, the company was reincorporated as Walt Disney Productions, Ltd. in 1929, and became publicity-traded as Walt Disney Productions in 1938. Walt Disney Productions established itself as a leader in the American animation industry before diversifying into live-action film production, television, and travel. Taking on its current name in 1986, The Walt Disney Company expanded its existing operations and also started divisions focused upon theatre, radio, publishing, and online media. In addition, it has created new divisions of the company in order to market more mature content than it typically associates with its flagship family-oriented brands.
The company is best known for the products of its film studio, the Walt Disney Motion Pictures Group, today one of the largest and best-known studios in Hollywood. Disney also owns and operates the ABC broadcast television network; cable television networks such as Disney Channel, ESPN, and ABC Family; publishing, merchandising, and theatre divisions; and owns and licenses 11 theme parks around the world. The company has been a component of the Dow Jones Industrial Average since May 6, 1991. An early and well-known cartoon creation of the company, Mickey Mouse, is the official mascot of The Walt Disney Company.
