Texas Instruments Incorporated
A maker of analog and embedded processing semiconductors, Texas Instruments supplies the power-management chips, microcontrollers, and processors inside cars, factories, phones, and data centers. It began in 1930 as Geophysical Service, a Dallas oil-exploration firm, renaming itself Texas Instruments in 1951. Three years later it built the first commercial transistor radio, and engineer Jack Kilby invented the integrated circuit there in 1958.
