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.[34] 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.
