Throughout the period, civic groups developed to work toward boosting the economy. The Terre Haute Committee for Area Progress developed the Fort Harrison Industrial Park in the 1970s. Grow Terre Haute in the mid-1980s encouraged the establishment of new stores, factories, and high-tech industrial parks that helped to stabilize the economy and enhance community life. Most encouraging were the arrival of the Digital Audio Disc Corporation (DADC), a subsidiary of the global company, Sony, as the first American factory designed exclusively to make compact discs. In other developments over these years, railroad overpasses eased traffic congestion, law enforcement strengthened, and several national and state awards for volunteerism and citizen participation boosted local pride.
