In 1945, stations WWJ and KDKA held competing 25th anniversary celebrations, both claiming to be the oldest "commercial radio station." Later that same year, KQW prepared and broadcast "The Story of KQW." The program made the claim that KCBS is the oldest radio station, predating by eleven years both WWJ and KDKA. This broadcast included a brief recorded statement by Herrold, made just before his 70th birthday. All three of these stations, WWJ, KDKA and KCBS, eventually came under the common ownership of CBS Radio and remain sister stations under the ownership of Entercom.
