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 American cinema. 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, music, and theatre divisions; and owns and licenses 14 theme parks around the world. The company has been a component of the Dow Jones Industrial Average since May 6, 1991.
