ABC (short for American Broadcasting Company) is a network founded by Edward Noble on October 12, 1943. It began on radio, but added a TV division on April 19, 1948. The network was bought by The Walt Disney Company in 1996 after buying Capital Cities a decade prior in 1986, and is best notable for being "saved" by the US version of the British game show Who Wants to Be a Millionaire?, which aired from 1999-2002 before moving to its current run in daily syndication. In 2006, it discontinued using the "ABC Sports" name for its sports broadcasts, opting for "ESPN on ABC" (as ESPN is also owned by Disney).
The network has been nicknamed the "Alphabet Network" as its name ironically implies the first 3 letters of the alphabet.
