The first issue of the Moline Daily Evening Dispatch was produced in July 31, 1878.
Since the Small Newspaper Group acquired the Argus in 1986, the two newspapers' operations have been combined over time. Today, the two newspapers' content is virtually identical, the only difference being that the mastheads are switched for readers in Moline and Rock Island.
In 1995 both papers switched from evening to morning publications. Quad-Cities Online has been operated by the papers since 1994. It provides local online news, weather, sports and event information.
