Texas Instruments was founded in 1951. It emerged after a reorganization of Geophysical Service. This company manufactured equipment for use in the seismic industry as well as defense electronics. TI began research in transistors in the early 1950s and produced the world's first commercial silicon transistor. In 1954, Texas Instruments designed and manufactured the first transistor radio and Jack Kilby invented the integrated circuit in 1958 while working at TI's Central Research Labs. The company produced the first integrated circuit-based computer for the U.S. Air Force in 1961. TI researched infrared technology in the late 1950s and later made radar systems as well as guidance and control systems for both missiles and bombs. The hand-held calculator was introduced to the world by TI in 1967.
In the 1970s and 80s the company focused on consumer electronics including digital clocks, watches, hand-held calculators, home computers as well as various sensors. In 1997, its defense business was sold to Raytheon. In 2007, Texas Instruments was awarded the Manufacturer of the Year for Global Supply Chain Excellence by World Trade magazine. Texas Instruments is considered to be one of the most ethical companies in the world.
