The Walt Disney Company, commonly known as Disney, is an American multinational mass media corporation headquartered at the Walt Disney Studios in Burbank, California. It is the largest media conglomerate in the world in terms of revenue. Disney was founded on October 16, 1923, by Walt Disney and Roy O. Disney as the Disney Brothers Cartoon Studio, and established itself as a leader in the American animation industry before diversifying into live-action film production, television, and theme parks. The company also operated under the names Walt Disney Studio and Walt Disney Productions. Taking on its current name in 1986, it expanded its existing operations and also started divisions focused upon theater, radio, music, publishing, and online media. In addition, Disney has created new corporate divisions in order to market more mature content than is typically associated with its flagship family-oriented brands.
The company is best known for the products of its film studio, the Walt Disney Studios, which is 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, A+E Networks, and ABC Family; publishing, merchandising, and theatre divisions; and owns and licenses 14 theme parks around the world. It also has a successful music division. 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 a primary symbol of The Walt Disney Company.
