Texas Instruments

What began as Geophysical Service Incorporated in 1930 has grown into a global semiconductor leader headquartered in Dallas. The company originated to support seismic exploration for the oil industry before pivoting toward electronics manufacturing during World War II. By 1951, it adopted the name Texas Instruments after developing radar jamming technology that proved vital to the war effort.

Jack Kilby invented the integrated circuit at TI labs in 1958, an achievement that earned him the Nobel Prize in Physics. This innovation followed the release of the first commercial silicon transistor in 1954. The firm later introduced the handheld calculator in 1967 and the single-chip microcontroller in 1970. A major strategic shift occurred in 1997 when the company divested its defense division to Raytheon to focus exclusively on digital solutions.

Today, over 80% of revenue comes from industrial, automotive, and enterprise applications rather than consumer goods. The acquisition of National Semiconductor in 2011 expanded their portfolio to approximately 45,000 analog products. While the brand remains culturally iconic for graphing calculators like the TI-84 series and DLP projection technology, the business model relies heavily on high-margin analog components critical for power management and signal processing.
