able to reenter the financial markets. In 1975, the corporation was reorganized and its mission expanded from developing housing to economic development. The finances were reorganized and the corporation assumed a less aggressive development stance, and its mission was refocused to finance other ambitious state projects and has been used frequently by governors to implement projects that circumvent formal Legislative or voter scrutiny. The move away from a housing mission began in the late 1970s and early 1980s with such projects as the Jacob K. Javits Convention Center and improvements to the Apollo Theater. Among its projects was a doubling of the New York state prison system, improvements to Love Canal, construction of the Jacob K. Javits Convention Center, revitalization of 42nd Street (Manhattan), revitalization of Niagara Falls, New York, construction of Battery Park City, development of Roosevelt Island, as well as planning for construction of a new Pennsylvania Station and for development of Governors Island.

A subsidiary, Lower Manhattan Development Corporation, and the World Trade Center Memorial Foundation were set up for those purposes. Rebuilding was financed by Liberty bonds. Whether the lack of public scrutiny has helped or hurt the development process can be debated. An audit released in May 2006 by New York comptroller Alan Hevesi reported that the Corporation loses track of its subsidiaries. At the time the corporation reported 70 active subsidiaries, but the audit showed there were 202 subsidiaries still legally on the
