William Randolph Hearst Sr. (; April 29, 1863 - August 14, 1951) was an American businessman, politician, and newspaper publisher who built the nation's largest newspaper chain and media company Hearst Communications and whose flamboyant methods of yellow journalism influenced the nation's popular media by emphasizing sensationalism and human interest stories. Hearst entered the publishing business in 1887 after being given control of The San Francisco Examiner by his wealthy father.

As biographer Ben Proctor explains:  During the 1920s he became an avowed Jeffersonian Democrat, warning his fellow citizens against the dangers of big government, of unchecked federal power that could infringe on the individual rights of Americans, especially if a charismatic leader was in charge....[After supporting FDR in 1932] Hearst soon became highly critical of the New Deal. With increasing frequency Hearst newspapers supported big business to the detriment of organized labor. With unabated vigor they condemned higher income tax legislation as a persecution of the "successful."  Hearst broke with FDR in spring 1935 when the president vetoed the Patman Bonus Bill for veterans and tried to enter the World Court. Hearst's papers were his weapon. They carried the publisher's rambling, vitriolic, all-capital-letters editorials, but he no longer employed the energetic reporters, editors, and columnists who might have made a serious attack. He reached 20 million readers in the mid 1930s, but they included much of the working class that Roosevelt had swept by three-to-one margins in the 1936 election. The Hearst papers--like most major chains--had supported the Republican Alf Landon that year.  In 1934, after checking with Jewish leaders to ensure a visit would be to their benefit, Hearst visited Berlin to interview Adolf Hitler. When Hitler asked why he was so misunderstood by the American press, Hearst retorted: "Because Americans believe in democracy, and are averse to dictatorship." Hearst's papers ran columns without rebuttal by Nazi leader Hermann Goring and Hitler himself, as well as Mussolini and other dictators in Europe and Latin America.
