Summa Corporation was aholding company for the business interests ofHoward Hughes after he sold the tool division ofHughes 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 themaster-planned community ofSummerlin, Nevada. Summa was renamed asThe Howard Hughes Corporation in 1994. It was acquired byThe Rouse Company in 1996.
This holding company contained Hughes' varied investments including:

Before 1972, Summa Corporation was namedHughes Tool Company. It was established in 1908 as a manufacturer of oil drilling tools. Under the ownership of Howard Hughes, the company expanded over the years into various other businesses, including aviation, media, and casino hotels.
In 1972, the company sold its tool business to investors via aninitial public offering as a new entity named Hughes Tool Company.[1][2] At that time, the parent company changed its name to Summa Corporation.[2] The name "Summa", Latin for "highest", was allegedly chosen by several of Hughes's employees without consulting him first. Hughes was allegedly dissatisfied, and preferred the name "HRH Properties", with the initials standing for both "Howard Robard Hughes" and "Hughes Resort Hotels", but his suggestion was ignored.
Howard Hughes died in 1976 at the age of 70,without a valid will.[3] Administrators were appointed, led by his cousin William Lummis. Under Lummis, Summa began to liquidate most of its operations. Summa's money-losing mining interests in Nevada were sold by the end of 1976, whileKLAS-TV andHughes Sports Network were both sold in 1978.Hughes Airwest was sold toRepublic Airlines for $38.5 million in October 1980,[4] andHughes Helicopters was sold toMcDonnell Douglas for $470 million in January 1984.[5] The hotel and casino properties were gradually sold off during the 1980s. As its original businesses were sold, Summa recast itself as a real estate developer, using the vast tracts of undeveloped land Hughes had amassed around Las Vegas as a starting point.
In September 1994, Summa Corporation was renamed The Howard Hughes Corporation, both to honor Howard Hughes and to fulfill his original intentions of keeping his name on the business.[6]
In February 1996, Hughes's heirs sold the Howard Hughes Corporation to theRouse Company for $520 million, plus half of any future profits from the company's undeveloped land holdings.[7]
The Rouse Company was, in turn, acquired byGeneral Growth Properties in November 2004.[8] A new company namedThe Howard Hughes Corporation was spun off from GGP in 2010 and is now a developer of master-planned communities.[9]
