The first -- and apparently only -- newspaper to partner with Clarence "C. S." Thompson and his Radio News and Music, Incorporated was the Detroit News. However, its station, WWJ, is still on the air.

WIRELESS  SENDS  AND  PICKS  UP  NEWS  ON  LARGE  SCALE
______

    The wireless telephone is being used for the first time as an actual medium of distributing news to the "reader." At the same time, in Cleveland, the first actual attempt is being made to gather news on a comprehensive scale by wireless.
    The Radio News and Music Company has been organized to establish sending stations in each city. From these stations news will be sent to owners of amateur wireless outfits. Local newspapers will be urged to take over the service as a means of increasing circulation.
    A huge wireless station capable of receiving messages from across the ocean was brought to Cleveland from Philadelphia for the Electrical Show by the United States Marines. Amateurs are asked to send fifty-word news bulletins to the station between 9 o'clock in the morning and midnight.
    The amateurs are requested to get their stories from newspaper offices of their localities. In many cases the newspapers have promised to give them the best local news stories of the day.
    The Thompson Company, World's Tower building, New York, is agent for the Radio News and Music Company.
