Hummers were originally the M998 High Mobility Multipurpose Wheeled Vehicle (HMMWV/Humvee) built by AM General Corporation for the US Army.
In 1992, AM General began selling cililian version of Humvee under the brand name "Hummer".
In 1998, AM General sold the brand name to the GM.
In mid 2008, due to the decreasing demand for large SUVs as a resule of rocketing oil prices, GM suggested the possibility of "Hummer" brand being sold.
On June 2, 2009, GM announced that the company has had a tentative deal to sell its Hummer brand to Chinese-based Sichuan Tengzhong Heavy Industrial Machinery Co., Ltd
