Corning Incorporated is an American manufacturer of glass, ceramics and related materials, primarily for industrial and scientific applications. The company was known as Corning Glass Works until 1989, when it changed its name to Corning Incorporated. While probably best known for its line of Corelle tableware and Pyrex cookware (businesses which it sold but still holds an ~8% interest in) Corning has transformed itself over the years into a high technology company, allocating a significant amount of resources towards research and development. As of 2008, Corning's businesses are broken down and focused into five major sectors: Display Technologies, Environmental Technologies, Life Sciences, Telecommunications and Specialty Materials. Corning is also involved in several joint equity ventures, the most notable being the Dow Corning Corporation.
