General Instrument (GI) was a diversified electronics manufacturer which specialised in semiconductors and cable television equipment. The company was active until 1997, when it split into General Semiconductor (power semiconductors), CommScope and NextLevel Systems (the cable and satellite TV division, which later reverted to GI name). The new (post-split) General Instrument Corporation was later acquired by Motorola and became the Motorola Connected Home Solutions division.
