Automotive industry in the United States

In the United States, the automotive industry began in the 1890s and, as a result of the size of the domestic market and the use of mass production, rapidly evolved into the largest in the world. The United States was the first country in the world to have a mass market for vehicle production and sales and is a pioneer of the automotive industry and mass market production process. During the 20th century, global competitors emerged, especially in the second half of the century primarily across European and Asian markets, such as Germany, France, Italy, Japan and South Korea. The U.S. is currently second among the largest manufacturers in the world by volume.
American manufacturers produce approximately 10 million units annually. Notable exceptions were 5.7 million automobiles manufactured in 2009 (due to crisis), and more recently 8.8 million units in 2020 due to the global COVID-19 pandemic. Production peaked during the 1970s and early 2000s at 13–15 million units.
Starting with Duryea in 1895, at least 1,900 different companies have been formed, producing over 3,000 makes of American automobiles. World War I (1917–1918) and the Great Depression in the United States (1929–1939) combined to drastically reduce the number of both major and minor producers. During World War II, all the auto companies switched to making military equipment and weapons. By the end of the 1950s the remaining smaller producers disappeared or merged into amalgamated corporations. The industry was dominated by three large companies: General Motors, Ford, and Chrysler, all based in Metro Detroit. Those "Big Three" continued to prosper, and the U.S. produced three-quarters of all automobiles in the world by 1950, 8.0 million out of 10.6 million produced. In 1908, 1 percent of U.S. households owned at least one automobile, while 50 percent did in 1948 and 75 percent did in 1960. Imports from abroad were a minor factor before the 1960s.
Beginning in the 1970s, a combination of high oil prices and increased competition from foreign auto manufacturers severely affected the US companies. In the ensuing years, the US companies periodically bounced back, but by 2008 the industry was in turmoil due to the aforementioned crisis. As a result, General Motors and Chrysler filed for bankruptcy reorganization and were bailed out with loans and investments from the federal government. June 2014 seasonally adjusted annualized sales were the biggest in history, with 16.98 million vehicles and toppled the previous record of July 2006. Chrysler later merged into Fiat as Fiat Chrysler and is today a part of the multinational Stellantis group. American electric automaker Tesla emerged onto the scene in 2009 and has since grown to be one of the world's most valuable companies, producing around 1/4th of the world's fully-electric passenger cars.
Prior to the 1980s, most manufacturing facilities were owned by the Big Three (GM, Ford, Chrysler) and AMC. Their U.S. market share has dropped steadily as numerous foreign-owned car companies have built factories in the U.S. As of 2012, Toyota had 31,000 U.S. employees, compared to Ford's 80,000 and Chrysler's 71,100.
