NISC was formed from the 2000 merger of North Central Data Cooperative (NCDC), Mandan, with Central Area Data Processing Corporation, St. Louis, Mo. NCDC was formed by electric and telephone cooperatives of the Dakotas in 1968.
To help tell its enduring story of cooperation on the occasion of its 50th anniversary, NISC has published “The Power of Possibility – 50 years of Innovation and Member Service.”
