The '' Chicago Sun-Times '' claims to be the oldest continuously published daily newspaper in the city . That claim is based on the 1844 founding of the '' Chicago Daily Journal '' , which was also the first newspaper to publish the rumor , now believed false , that a cow owned by Catherine O'Leary was responsible for the Chicago fire . The '' Evening Journal '' , whose West Side building at 17 – 19 S. Canal was undamaged , gave the '' Chicago Tribune '' a temporary home until it could rebuild . Though the assets of the '' Journal '' were sold to the '' Chicago Daily News '' in 1929 , its last owner Samuel Emory Thomason also immediately launched the tabloid '' Chicago Daily Illustrated Times ''
