University of Illinois system
By 1967 the University of Illinois system consisted of a main campus in Champaign-Urbana and two Chicago campuses, Chicago Circle (UICC) and Medical Center (UIMC), and people began using "Urbana-Champaign" or the reverse to refer to the main campus specifically. The university name officially changed to the "University of Illinois at Urbana-Champaign" by 1977. While this was a reversal of the commonly used designation for the metropolitan area, "Champaign-Urbana," most of the campus is located in Urbana. The name change established a separate identity for the main campus within the University of Illinois system, which today includes campuses in Springfield (UIS) and Chicago (UIC) (formed by the merger of UICC and UIMC).
