Company Overview<\/h2>\n

General Instrument was founded in 1939. GI was a manufacturer of transistors and diodes in the 1950’s and 1960’s. General Instrument produced logic chips in the 1960’s. GI created the PIC (Programmable Intelligent Computer) line of microprocessors in 1976. The microprocessors along with the rest of the Microelectronics Division were spun-off as Microchip Technology in 1989. in 1997, the remaining company, which is most noted for its work with advanced TV and broadband technologies, was restructured and split into three public companies.<\/p>\n

This is an interesting branding effort GI used to make sure General Transistor customers knew that GT had become GI.\u00a0 The General Transistor logo at left morphs into the GI logo on the right.
