Despite the setback with FM, the Yankee Network seemed to be doing well. There were a number of popular programs, including "Ruth Moss Interviews," featuring conversations with local and national celebrities; a variety show called "Yankee House Party," featuring organist Frank Cronin and the Bobby Norris Orchestra, which was also picked up by the Mutual Network; as well as various sports events, including Red Sox and Braves play-by-play, often announced by Jim Britt, who had been hired as a sportscaster by the Yankee Network in 1939. In mid-1941, it was announced that the network would soon change from its affiliation with NBC to a full-time affiliation with Mutual. In March 1942, the network debuted six new studios, including one especially equipped for FM, as well as several with better acoustics and new musical instruments for the Yankee Network's orchestras; one studio featured a custom-designed organ, said to be the largest in use at any radio station.
