History of the American Broadcasting Company

The American Broadcasting Company is an American multinational commercial broadcast television network that is a flagship property of Walt Disney Television, a subsidiary of the Disney Media Networks division of The Walt Disney Company. The network is headquartered in Burbank, California, on Riverside Drive, directly across the street from Walt Disney Studios and adjacent to the Roy E. Disney Animation Building. The network's secondary offices, and headquarters of its news division, is in New York City, at its broadcast center at 77 West 66th Street on the Upper West Side of Manhattan.

The network's history dates back to 1927, when the network was created as an NBC-operated radio network called the NBC Blue Network. It would later become an independent television network known as the American Broadcasting Company in 1943, and be purchased by The Walt Disney Company in 1995.
Blue Network
In the 1930s, radio in the United States was dominated by three companies: the Columbia Broadcasting System , the Mutual Broadcasting System, and the National Broadcasting Company . The last was owned by electronics manufacturer Radio Corporation of America , which owned two radio networks that each ran different varieties of programming, NBC Blue and NBC Red. The NBC Blue Network was created in 1927 for the primary purpose of testing new programs on markets of lesser importance than those served by NBC Red, which served the major cities, and to test drama series.
