Enclosing some 3.9 million ft² (360,000 m²) in exhibition space and hosting more than a million visitors each year, the GWCC is the third-largest convention center in the United States. Opened in 1976, the GWCC was the first state-owned convention center established in the United States. The center is operated on behalf of the state by the Georgia World Congress Center Authority, which was chartered in 1971 by Georgia General Assembly to develop an international trade and exhibition center in Atlanta.
