ABC Radio originally began after the split of NBC Red and NBC Blue (later Blue Network) networks with ABC taking over operations of the latter from RCA in 1943 before adopting its name 2 years later. ABC Radio was known to broadcast the first nationwide report of the assassination of President John F. Kennedy. Kennedy was shot in a motorcade in Dallas, Texas, at 18:30 UTC on November 22, 1963, and ABC Radio's Don Gardiner anchored the network's initial bulletin at 18:36:50 UTC, minutes before any other radio or television network followed suit.
