In 2007, Fortune magazine named ONEOK the most admired company in the energy industry. ONEOK’s predecessor, Oklahoma Natural Gas Company (ONG), had been headquartered in an Art Deco building on the northwest corner of Seventh Street and Boston Avenue in Tulsa since 1928. In 1982, ONEOK chairman, J. E. Tyree, announced plans to demolish the ONG building and replace it with a new 16-story tower. However, this did not happen. Instead, ONEOK bought the Cities Service Company (later renamed Citgo) in August, 1982. The acquired company already had a project underway to build a high-rise headquarters building at Fifth and Boulder. ONEOK realized that it would be more economical to cap the planned structure at 17 stories and move its headquarters there, rather than to proceed with its original plan. It completed the new black granite and glass tower in 1984. In 2009, ONEOK sponsored the construction of ONEOK Field, the new Tulsa Drillers minor league baseball stadium in downtown Tulsa.
