Challenge: Hearst actually does acquire the *Chicago Tribune*...
Hearst of course had his own Chicago newspaper in 1941, the *Chicago Herald-American* which would become simply the *Chicago American* and eventually (1956) be bought by the *Tribune*; it would be renamed *Chicago's American* and then *Chicago Today* until its demise in 1974.
(Mawdsley is in general a fine historian, btw. But sometimes even Homer nods.)
