had a continuous history as the "Detroit News Radiophone" dating to August 20, 1920. After leasing 8MK's DeForest OT-10 transmitter through Radio News & Music, the newspaper had assumed total responsibility for constructing and running the radio station, including hiring engineers and staff. The transfer from operating under 8MK's license to that of WBL's had minimal effect. The same DeForest OT-10 transmitter was being used, operating from the same location, and under the control of the same Detroit News employees who had been responsible for the 8MK broadcasts. Moreover, at the time of the switchover from 8MK to WBL, the News had informed its readers that, although the call sign and operating frequency were changing, the paper's broadcast service would continue, and "The Detroit News radio station... will transmit as before." Publicity issued by WWJ regularly listed August 1920 as its founding date, but varied greatly when describing the station's historical significance. In an early example, a 1922 advertisement for the Detroit News merely stated that the paper deserved recognition for having "installed the first transmitting set in use by any newspaper." (At this time there was at least one other broadcasting station with a strong claim to predate both 8MK/WWJ and 8ZZ/KDKA, KZY in Oakland, California, which was a re-licensing of an experimental station: 6XC in San Francisco, also known as the "California Theater Station." 6XC had begun a wide-ranging selection of daily broadcasts around April 1920, and in 1921 Lee de Forest wrote that this was the "first radio-telephone station devoted solely" to broadcasting to the public. However, KZY would be deleted in early 1923.) Later reviews became more sweeping in their claims. In 1934, an advertisement for WWJ included the contention that it was "America's Pioneer Broadcasting Station." While celebrating its 25th anniversary in August 1945, WWJ further claimed to have been the station where "commercial radio broadcasting began." ("First commercial station" status was also claimed by KDKA, in spite of the fact that both WWJ and KDKA were initially commercial-free and did not start to accept advertising until the mid-1920s, so in this case "commercial" appears to only mean that the station was under the control of a commercial enterprise.) Largely ignored by WWJ and KDKA was a third station that had been reviewed in the Baudino and Kittross article, KCBS in San Francisco, which contended it was significantly older than both WWJ and KDKA.
