77 WABC Radio
Owned and operated by the American Broadcasting Company for much of its history, it is one of the country's oldest radio stations. WABC began broadcasting in early October 1921, originally as WJZ in Newark, New Jersey. From 1943 through 2007, the station served as the flagship for the original ABC Radio Network (and its direct predecessor, the Blue Network) and ABC's radio news service. While WABC has been a talk radio station since 1982, the station broadcast a Top 40 music format from 1960 to 1982. Starting in the 1960s to 1978, WABC was not only the dominant contemporary music station in New York City, but was also among the most listened-to radio stations in North America, serving as a template for many other Top 40 stations around the country.
