Since the 1950s and 1960s Muncie has continued as an education center in the state and emerged as a regional health center. As enrollment at Ball State increased, new buildings were erected on the college's campus. Ball Memorial Hospital also expanded its facilities. However, by the 1960s, industrial trends had shifted. Beginning in the 1970s several manufacturing plants closed or moved elsewhere, while others adapted to industrial changes and remained in Muncie. Ball Corporation, for example, closed its Muncie glass manufacturing facilities in 1962 and its corporate headquarters relocated to Broomfield, Colorado in 1998. Muncie was also home to other manufacturing operations, including Warner Gear (a division of BorgWarner), Delco Remy, General Motors, Ontario Corporation, A. E. Boyce Company, and Westinghouse Electric, among others.
