Printing industry 
After World War II, Sparta became known as "Magazineland, U.S.A." due to the presence of numerous printing plants that produced most of the mass-market color comic books in the United States. Spartan Printing employed as many as 1,000 people at its peak. Later, major comics distributors situated their warehouses in and around Sparta.
World Shooting and Recreational Complex 
In 2005, the Amateur Trapshooting Association (ATA) voted to move its headquarters from Vandalia, Ohio, to Sparta. The city and state governments had lobbied hard for the move to Sparta, which was necessitated by the expansion of the Dayton International Airport in Vandalia.
In 2006, then Illinois Governor Rod Blagojevich and local dignitaries opened the World Shooting and Recreational Complex north of Sparta. The ATA hosted its first Grand American at the facility in August, with several thousand shooters attending.
In 2012 the ATA moved their national headquarters to 1105 East Broadway, Sparta Illinois. All day to day operations for the Association are now handled at this location.
