Westinghouse Electric Corporation
Westinghouse was a diversified company. It was involved in a wide variety of products and services. The company had a number of firsts. It produced the first jet engine in the United States and the first nuclear power plant. It also developed the first U.S. radar station (used at Pearl Harbor). In the late 1980s a number of bad business decisions caused the company to decline. After selling off most of its manufacturing divisions, Westinghouse Electric took the name of one of its subsidiaries, CBS, which it bought in 1995.
