GM was the leader in total worldwide vehicle sales for 77 consecutive years, from 1931 to 2007, staying on top longer than any other auto manufacturing production company. GM remains the world’s largest automaker in regard to vehicle unit sales.
In 2009, GM went through a company reorganization backed by the government after a Chapter 11 filing for bankruptcy. The same year, the company ceased production of several brands, letting go of Hummer, Saturn and Pontiac. After lightening its brand production load and with the government-backed restructuring, GM made one of the top five world's largest initial public offerings in 2010 to raise needed capital.

In an attempt to cash in on the push for alternate fuel cars, GM pioneered the first all-electric vehicle of the modern age, offering the first concept car with zero emissions marketed in the United States. In 2008, the company committed to making about half of its manufacturing plants completely landfill-free. The company recycles or otherwise reuses all production waste from its manufacturing processes.
