Texas Instruments (TI) is an American multinational semiconductor company headquartered in Dallas, Texas, that designs and manufactures analog chips, embedded processors, and digital light processing (DLP) technology. Originally emerging in 1951 from the reorganization of Geophysical Service Incorporated—a company founded in 1930 to manufacture equipment for the seismic industry and defense electronics—TI quickly became a pioneer in the electronics industry. The company produced the world's first commercial silicon transistor and designed the first transistor radio in 1954. A major breakthrough occurred in 1958 when Jack Kilby invented the integrated circuit at TI's Central Research Labs. The company continued its history of innovation by inventing the handheld calculator in 1967 and introducing the first single-chip microcontroller in 1970. In 1987, TI invented the digital light processing device, which became the foundation for its DLP Cinema technology. The company also became a leader in the graphing calculator industry following the release of the popular TI-81 calculator in 1990. To strengthen its focus on digital solutions, TI sold its defense business to Raytheon Company in 1997. Following its acquisition of National Semiconductor in 2011, the company expanded its portfolio to include tens of thousands of analog products and customer design tools.
