The newspaper was founded as the Madison Intelligencer in 1862; it was a Democratic newspaper.[1][2][3] It was published by James R. Brown and Henry C. Barnsback.[1] In 1868, it became the Edwardsville Intelligencer.[4]
A building for the newspaper office was constructed for Charles Boeschenstein[5] near the courthouse at 108 St. Louis Street.[2] In 1923, the paper moved to 117 N Second Street.[6]
On November 14, 1937, the Intelligencer published a special 75th Anniversary edition, which included history of Edwardsville and Madison County.[7] In 1962, the Intelligencer joined the Granite City Press-Record and the Alton Telegraph to publish a sesquicentennial history of Madison County.[8]
In 2019, the Intelligencer switched from route delivery to US Postal Service delivery.[11] On May 29, 2019, the newspaper office moved to its current headquarters on 116 North Main Street.[12][13] In 2020, the building on Second Street became a venue called The Ink House with newspaper-themed rooms such as "The Press Room" and "Off the Record".[14][6]
