History

History of the WJZ call letters

The WJZ callsign was first used on what is now WABC in New York City. The original Westinghouse Electric Corporation, whose broadcasting division is a predecessor to the current broadcasting unit of CBS Corporation, launched WJZ in 1921, and was located originally in Newark, New Jersey. WJZ was sold in 1923 to the Radio Corporation of America, who moved its operations to New York, and on January 1, 1927, WJZ became the flagship station for the NBC Blue Network. (In the 1929 movie The Cocoanuts the station was name-checked by Chico Marx in a sequence of running gags between Chico and Groucho: Chico uses the station's call-sign as the punchline of a punning joke based on his confusion over the meaning of the word "radius", which he confuses with 'radios', leading to the mention of the station's call-sign.) NBC Blue would become the American Broadcasting Company in 1942. ABC later established WJZ-FM and WJZ-TV at the same time in 1948.
