Flying above the intersection of Interstates 287 and 684 in White Plains, N.Y., we're looking down at an office building at 1133 Westchester Avenue, which was for more than three decades the flagship of IBM's marketing and services organization in the United States.
During the 1970s "Eleven Thirty-three" served as the headquarters of the "big iron" Data Processing Division (DPD), and in January 1982 it became the head office of DPD's successor: the National Accounts Division (NAD). Four years later, NAD was succeeded by the North-Central Marketing Division (NCMD), and 1133 then housed the home office of an IBM marketing territory covering 23 states and Puerto Rico. In July 1988, NCMD was consolidated into U.S. Marketing & Services, which also maintained its headquarters at 1133.
In more recent years, the 560,000-square foot building was occupied by about 2,200 employees of IBM's global sales and distribution organization and several other staffs. In 2005, the site became a multi-tenant facility, with the south wing partially occupied by Starwood Hotels & Resorts Worldwide Inc., and a year later, IBM moved many of its remaining employees from 1133 to other nearby sites in Westchester.
