Corning Incorporated is an American multinational technology company specializing in glass, ceramics, and related materials and technologies including advanced optics, primarily for industrial and scientific applications. Founded in 1851, the company was called Corning Glass Works for most of its history. Corning was known during the 20th century for its consumer product lines, such as including CorningWare and Visions Pyroceram-based cookware, Corelle Vitrelle tableware, and Pyrex glass bakeware. It divested its consumer product lines in 1998 by selling the Corning Consumer Products Company to Borden. As of 2014, Corning had five major business sectors: display technologies, environmental technologies, life sciences, optical communications, and specialty materials. Corning is involved in two joint ventures: Dow Corning and Pittsburgh Corning. The company completed the corporate spin-offs of Quest Diagnostics and Covance in January 1997. Corning develops and manufactures Gorilla Glass, which is used by many smartphone makers. It is one of the world's biggest glassmakers. Corning is one of the main suppliers to Apple Inc. since working with Steve Jobs in 2007 to develop the iPhone.
