By 1929, General Motors had exceeded the Ford to become the number one automaker in America. It introduced overseas operations including the Vauxhall of Britain in 1925, the Adam Opel of Germany in 1929, and the Holden of Australia in 1931. The Yellow Truck & Coach Manufacturing Company, which was organized in 1925, was one of the new American divisions and subsidiaries set up. In 1931, GM became the world's largest producer of motor vehicles. This manufactured 44% of all U.S. vehicles in 1941 and became one of the largest industrial companies in the world. GM grew in the 1950s and 1960s along with the American economy and continued to hold 40% to 45% of total U.S. automotive sales. In 1984, it bought Electronic Data Systems Corporation, a large data processing company, and in 1986 it acquired the Hughes Aircraft Company, a manufacturer of weapons systems and satellites for communication. In the 1970s and 1980s, together with other United States car manufacturers, the corporation endured increasingly intense competition from Japan’s car makers, and in 1984 General Motors started a new automotive subsidiary, Saturn, which used highly automated factories to create smaller vehicles to cope with Japanese imports. While the restructuring efforts of General Motors saw some promise, substantial losses in the early ‘90s forced the company to shut down several factories and fire thousands of its employees.
