3 manufacturer of semiconductors worldwide after Intel and Samsung, and is the top supplier of chips for cellular handsets, as well as the No. 1 producer of digital signal processors (DSPs) and analog semiconductors . Other focus areas include chips for broadband modems, PC peripherals, digital consumer devices, telecommunication infrastructure, and Radio Frequency Identification (RFID). As of 2006, the company was listed at number 167 on the Fortune 500.

History

Texas Instruments was founded by Cecil H. Green, J. Erik Jonsson, Eugene McDermott, and Patrick E. Haggerty. On December 6, 1941, they purchased Geophysical Service Incorporated (GSI), a pioneering provider of seismic exploration services to the petroleum industry. During World War II, GSI built electronics for the U.S. Army Signal Corps and the U.S. Navy. After the war, GSI continued to produce electronics, and in 1951 the company changed its name to Texas Instruments; GSI became a wholly owned subsidiary of the new company. An early success story for TI-GSI came in the 1950s when GSI was able (under a Top Secret government contract) to monitor the Soviet Union's underground nuclear weapons testing from outcrop bedrock found in Oklahoma.

In 1954, TI designed the first transistor radio. Also in the 1950s, the integrated circuit was developed independently by Jack Kilby of TI and Robert Noyce of Fairchild Semiconductor. Kilby's patent for a "solid circuit" was filed in 1958. The 7400 series of transistor-transistor logic (TTL) chips, developed by TI in the 1960s, popularized the use of integrated circuits in computer logic, and is in widespread use to this day. TI also invented the hand-held calculator in 1967, the single-chip microcomputer in 1971 and was assigned the first patent on a single-chip microprocessor (invented by Gary Boone) in 1973. (Note: TI is usually given credit with Intel for the almost-simultaneous invention of the microprocessor.)

TI also continued to manufacture equipment for use in the seismic industry, and GSI continued to provide seismic services. After selling (and repurchasing) GSI, TI finally sold the company to Halliburton in 1988, at which point GSI ceased to exist as a separate entity.

TI had two interesting problems with engineering and product development after the introduction of the semiconductor and the microprocessor. Firstly, most of the chemicals, machinery and technologies needed to create semiconductors did not exist so TI had to "invent" them. Secondly, the market was small for TI electronic components in the early days so TI had to "invent" uses to create the markets. For example, TI created the first wall mounted, computer controlled, home set-back thermostat in the late '70s but nobody would buy it mostly because of its cost. TI started an Industrial Controls division which built automated process control computers used in the paint and soup industry and was very successful. This business was eventually sold to Siemens AG in 1991. TI turned to military and government uses and had many electro-mechanical devices used in the Apollo rocket and moon lander.
