The dual-entranced Target Greatland prototype debuted -in Apple Valley, Minnesota- in 1990. Larger than a standard Target, it was strictly a general merchandise operation, with no grocery section.

The Dayton Hudson Corporation introduced the SuperTarget ("SuperT") store format -in Omaha, Nebraska- in 1995. A SuperT included full lines of general merchandise, as well as a supermarket.
