Corning Inc was incorporated in the State of New York in December 1936. The Company's name was changed from Corning Glass Works to Corning Incorporated on April 28, 1989. The Company is engaged in manufacturing of specialty glass and ceramics. It operates in five reportable segments: Display Technologies, Optical Communications, Environmental Technologies, Specialty Materials and Life Sciences. The Display Technologies segment manufactures glass substrates for active matrix liquid crystal displays (LCDs) that are used in LCD televisions, notebook computers and flat panel desktop monitors. This segment develops, manufactures and supplies high quality glass substrates using technology expertise and a proprietary fusion manufacturing process, which Corning invented and is the cornerstone of the Company's technology leadership in the LCD industry. The Optical Communications segment is classified into two main product groupings - carrier network and enterprise network. The carrier network product group consists of products and solutions for optical-based communications infrastructure for services such as video, data and voice communications. The enterprise network product group consists of optical-based communication networks sold to businesses, governments and individuals for their own use. The Environmental Technologies segment manufactures ceramic substrates and filter products for emissions control in mobile and stationary applications around the world. The Specialty Materials segment manufactures products that provide more than 150 material formulations for glass, glass ceramics and fluoride crystals to meet demand for customer needs. Consequently, this segment operates in a wide variety of commercial and industrial markets that include display optics and components, semiconductor optics components, aerospace and defense, astronomy, ophthalmic products, telecommunications components and cover glass that is optimized for portable display devices.
