The Howard Hughes Corporation is a real estate development and management company based in The Woodlands, Texas. It began as part of the oil drilling tool business founded by Howard R. Hughes, Sr., in 1913, which under his son Howard Hughes, Jr., diversified into real estate development. The real estate operations became a separate company, which was acquired by The Rouse Company, which in turn was acquired by General Growth Properties (GGP). In 2010, GGP spun off The Howard Hughes Corporation as a separate company.
