Home Hour brought news and entertainment to rural listeners. Ted Malone read poetry and Milton Cross conveyed children "Coast To Coast on a Bus", as well as bringing opera lovers the Saturday matinée Metropolitan Opera radio broadcasts. Cross would continue to host the Met on NBC, ABC, CBS and NPR until his passing at the beginning of 1975. Occasionally, a show would premiere on NBC Blue, which had a weaker lineup of stations nationwide, and be shifted to the Red Network if it grew in popularity. Fibber McGee and Molly is one example. When the FCC limited broadcast stations to 50 kW, a 500 kW transmitter built by RCA for WJZ was no longer allowed. The transmitter was sold by RCA to Britain and used for wartime Black Propaganda; broadcasting as Soldatensender Calais a purported German military station. Birth of ABC In 1942, the FCC ruled that no broadcaster could own more than one AM, one FM and one television station in a single market. On January 23, 1942, the FCC approved the transfer of WJZ's operating license from Radio Corporation of America to the Blue Network, Inc. A year later, on October 12, 1943, WJZ and the NBC Blue Network were sold to Edward J. Noble, then the owner of WMCA. Technically, this spun off network was simply called "The Blue Network" for little over a year. On June 15, 1945, "The Blue Network" was officially rechristened the American Broadcasting Company, when negotiations were completed with George B. Storer, who had owned the defunct American Broadcasting System and still owned the name. In November 1948, WJZ and the ABC network finally got a home of their own when studios were moved to a renovated building at 7 West 66th Street. On March 1, 1953, WJZ changed its call letters to WABC, after the FCC approved ABC's merger with United Paramount Theatres, the movie theater chain owned by Paramount Pictures which, like the Blue Network, was divested under government order. The WABC call letters were previously used on CBS Radio's New York City AM and FM outlets, reflecting an earlier owner, the Atlantic Broadcasting Company. On November 1, 1946, WABC (AM) changed its call sign to WCBS, and the FM station became WCBS-FM. In 1957, several years after WJZ's callsign change to WABC, Westinghouse Broadcasting acquired WAAM-TV in Baltimore, Maryland, and applied to change the calls to WJZ-TV, in honor
