Daily newspaper published in Chicago.
The Tribune is one of the leading U.S. newspapers and long has been the dominant voice of the Midwest. Founded in 1847, it was bought in 1855 by six partners, including Joseph Medill (1823–99), who made the paper successful and increased its stature while promulgating his generally liberal views. He bought a controlling interest in 1874 and was publisher until his death. During Robert McCormick 's tenure (1914–55), the paper achieved the largest circulation among U.S. standard-sized newspapers and led the world in newspaper advertising revenue. The Tribune also reflected his nationalist-isolationist views, but its editorial positions moderated after his death. It subsequently became the flagship of the Tribune Company, which has holdings in broadcasting, cable TV, publishing, and other media.
