The Chicago Tribune is a major daily newspaper based in
Chicago, Illinois, and the flagship publication of the
Tribune Company. Formerly self-styled as the "World's
Greatest Newspaper" (for which WGN radio and
television is named), it remains the most read daily
newspaper of the Chicago metropolitan area and the Great
Lakes region and is currently the eighth largest newspaper
in America by circulation (and the second largest under
Tribune's ownership behind Los Angeles Times). Traditionally
published as a broadsheet, on January 13, 2009, the Tribune
announced it would continue publishing as a broadsheet for
home delivery, but would publish in tabloid format for
newsstand, news box, and commuter station sales.
