Connected to the main tower is a four-story radio and television broadcasting facility where WSNS's newscasts and WMAQ's newscasts are currently taped, and was the former recording facility for Jerry Springer and The Steve Wilkos Show before their tax credit-influenced move to Stamford, Connecticut in 2009.

The tower was also the world headquarters of Navistar International until 2000 when the company announced plans to relocate to west suburban Lisle, Illinois.
