Summa Corporation was a holding company for the business interests of Howard Hughes after he sold the tool division of Hughes Tool Company in 1972. Its holdings included casino hotels, aviation businesses, and television channels. After Hughes's death in 1976, most of the company's assets were sold off, and it focused on developing the master-planned community of Summerlin, Nevada. Summa was renamed as The Howard Hughes Corporation in 1994. It was acquired by The Rouse Company in 1996.
