The Press-Radio War in the United States lasted from 1933 to 1935. Newspaper publishers were concerned to maintain their own dominance of the news market in the face of the emerging radio networks. The Press induced the wire services to stop providing news bulletins to radio broadcasters, which then developed their own news-gathering facilities. In response the press launched political, economic and legal campaigns to prevent news being broadcast on radio, culminating in The Biltmore Agreement by which major networks were compelled to heavily restrict radio news coverage. However, broadcasters soon developed ways to subvert the terms of this agreement, including the use of newly established news agencies such as the Transradio Press Service.
