The National Broadcasting Company (NBC) is one of the four major television networks in the United States. From 1961 to 1981, and 1988 to 1990, it aired the Disney anthology television series, which first ran on ABC from 1954 to 1961 as Disneyland. Upon its move to NBC, it changed its name to Walt Disney's Wonderful World of Color, and later renamed Wonderful World of Disney. From 1985 to 1989, Disney's first animated television series, Adventures of the Gummi Bears, aired on NBC on Saturday mornings.
Today, NBC is a subsidiary of NBC Universal, which, in turn, is owned by General Electric. In 2009, it was announced that cable system owner Comcast would gradually take over NBC Universal operations from GE, paying US $20 billion over a ten year period.
