Created and maintained by Aaron Moore, a professor of sports media at Ithaca College, this Web page documents which publications (and other ancillary businesses) are owned and controlled by various media conglomerates around the United States. Some of the media conglomerates covered by this rather revealing site include such newer upstarts in the media business such as Clear Channel Communications (which owns hundreds of radio stations around the United States), and a few of the more venerable media moguls, including the Hearst Corporation and the Tribune Company. Along with listing the holdings of these various corporations, the site includes a number of articles from the Columbia Journalism Review that deal with media ownership. One rather fascinating article addresses the life and career of Dean Singleton, CEO of the privately held MediaNews Group, which is the seventh-largest newspaper company in the U.S.
