Newspapers, like other media, were controlled by the state; the Reich Press Chamber shut down or bought newspapers and publishing houses. By 1939, over two-thirds of the newspapers and magazines were directly owned by the Propaganda Ministry.[453] The NSDAP daily newspaper, the Völkischer Beobachter ("Ethnic Observer"), was edited by Rosenberg, who also wrote The Myth of the Twentieth Century, a book of racial theories espousing Nordic superiority.[454] Goebbels controlled the wire services and insisted that all newspapers in Germany only publish content favourable to the regime.
