GM Timeline

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. The stock trades under the ticker symbol GM.

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.

In 2017, GM acquired Strobe, a developer of sensors to track distances, to help develop technology for future self-driving cars. It also unveiled the Chevy Bolt, an autonomous self-driving vehicle, in 2017. In 2018, General Motors announced that Honda was investing $2.75 billion in GM's self-driving car unit.
