The building was built to replace the Southwestern Bell Building as the Southwestern Bell world headquarters. However, in a series of mergers the headquarters moved to San Antonio, Texas and was later renamed AT&T.

In 2006 Inland American Real Estate Trust, a subsidiary of the Inland Real Estate Group in Chicago bought the building for $205 million. AT&T then signed a 10-year lease to be the sole tenant.[6]

At one point, 4,800 AT&T employees worked in the building but that number has dropped through layoffs, outsourcing and telecommuting to approximately 2,000. In September 2013, AT&T announced they would vacate the building over the next 12 months, although their lease on the building runs through 2017.[7]
