Oldsmobile was a brand of automobile produced for most of its existence by General Motors. It was founded by Ransom E. Olds in 1897. In its 107-year history, it produced 35.2 million cars, including at least 14 million built at its Lansing, Michigan factory. When it was phased out, Oldsmobile was the oldest surviving American automobile marque, and one of the oldest in the world, after Daimler and Peugeot. It is GM's first brand to be phased out in the 21st century, after the company's Geo and Canadian-market Asüna brands were phased out in the early 1990s.
