Since the 1980s, Disney has created and acquired corporate divisions in order to market more mature content than is typically associated with its flagship family-oriented brands. The company is known for its film studio division, The Walt Disney Studios, which includes Walt Disney Pictures, Walt Disney Animation Studios, Pixar, Marvel Studios, Lucasfilm, 20th Century Studios, Searchlight Pictures, and Blue Sky Studios. Disney's other main business units include divisions in television, broadcasting, streaming media, theme park resorts, consumer products, publishing, and international operations. Through these various segments, Disney owns and operates the ABC broadcast network; cable television networks such as Disney Channel, ESPN, Freeform, FX, and National Geographic; publishing, merchandising, music, and theater divisions; direct-to-consumer streaming services such as Disney+, Hulu, ESPN+ and Hotstar; and Disney Parks, Experiences and Products, a group of 14 theme parks, resort hotels, and cruise lines around the world. Cartoon character Mickey Mouse, created in 1928 by Walt Disney and Ub Iwerks, is one of the world's most recognizable characters and serves as the company's official mascot.
