Hummer is an American automotive brand first introduced in 1992. The Hummer brand was created by AM General as a way to market their civilian versions of the military Humvee. The first offering by Hummer was the H1, yet after AM General sold the brand to General Motors in 1999, Hummer would also introduce the H2 and H3 models. After initial success, the company saw a decline in fortunes, with GM eventually discontinuing Hummer in 2010.
