Times Square Studios is owned by The Walt Disney Company, a media and entertainment conglomerate, which also owns ABC. It was designed by Walt Disney Imagineering, Disney's design and development arm. The original concept for the studio was conceived by Harry Grossman. His plan called for the studio to broadcast many shows twenty-four hours a day for both Disney-owned and non-Disney programs. The core management staff is Jeff Hartnett, Robert Agnello and Maura Hayes. The studio's site is the former National Theater and Beefsteak Charlie's.
