American automobile industry in the 1950s
In 1954, the smaller American Motors Corporation (AMC) was formed when Hudson merged with Nash-Kelvinator Corporation in a deal worth almost USD $200 million ($1.735 billion in 2013 dollars) the largest corporate merger in U.S. history at that time. Other mergers with smaller independent manufacturers followed. Although AMC was moderately successful it was never sufficiently large to challenge any of the Big Three, and was eventually bought by Chrysler in 1987.
Nash Motors
In January 1954 Nash announced the acquisition of the Hudson Motor Car Company as a friendly merger, creating American Motors Corporation (AMC). To improve the financial performance of the combined companies, all production beginning with the 1955 Nash and Hudson models would happen at Nash's Kenosha plant. Nash would focus most of its marketing resources on its smaller Rambler models, and Hudson would focus its marketing efforts on its full-sized cars.
