Fairchild Semiconductor
In 1979, Fairchild Camera and Instrument (including Fairchild Semiconductor) became a subsidiary of Schlumberger. Schlumberger sold Fairchild Semiconductor to National Semiconductor in 1987; National Semiconductor was then acquired by Texas Instruments in 2011. The rest of Fairchild was renamed Fairchild Weston Systems in 1982, which was bought by Loral Corporation in 1989. The company was then renamed as the Loral Fairchild Systems division of Loral Corp.
