The American Broadcasting Company (ABC) is an American commercial broadcast television and radio network that serves as the flagship property of the Disney Entertainment division of the Walt Disney Company. ABC is headquartered on Riverside Drive in Burbank, California, directly across the street from Walt Disney Studios and adjacent to the Team Disney – Roy E. Disney Animation Building. The network maintains secondary offices at 7 Hudson Square in New York City's Lower Manhattan neighborhood, which houses its broadcast center and the headquarters of its news division, ABC News. Until early 2025, the network's East Coast operations were based at 77 West 66th Street on the Upper West Side of Manhattan. Since 2007, when ABC Radio (also known as Cumulus Media Networks) was sold to Citadel Broadcasting, ABC has reduced its broadcasting operations almost exclusively to television. The youngest of the "Big Three" American television networks, the network is sometimes referred to as the Alphabet Network, as its initialism also represents the first three letters of the English alphabet in order.
ABC launched as a radio network in 1943, as the successor to the NBC Blue Network, which had been purchased by Edward J. Noble. It extended its operations to television in 1948, following in the footsteps of established broadcast networks CBS and NBC, as well as the lesser-known DuMont. In the mid-1950s, ABC merged with United Paramount Theatres (UPT), a chain of movie theaters that formerly operated as a subsidiary of Paramount Pictures. Leonard Goldenson, who had been the head of UPT, made the then-new television network profitable by helping to develop and green-light many successful television series. In the 1980s, after purchasing an 80 percent interest in cable sports channel ESPN, the network's corporate parent, American Broadcasting Companies, Inc., merged with Capital Cities Communications, owner of several television and radio stations and print publications, to form Capital Cities/ABC Inc., which in turn merged into Disney in 1996.
