Texas Instruments Alive
Kilby's integrated circuit, the Speak & Spell, the TI-99/4A, and the Explorer Lisp machine — plus decades of the DSP market nobody talks about.
Geophysical Service Inc. (1930) became Texas Instruments in 1951. Jack Kilby demonstrated the first working integrated circuit there in 1958 — the Nobel he won in 2000 was essentially for inventing the industry.
TI built the first transistor radio (1954), the first handheld calculator, the Speak & Spell (1978), and the TI-99/4A home computer (1979–84, a price-war casualty). Its DSP business and analog chips fund everything since.
