General Instrument (GI) was an electronics manufacturer based in Horsham, Pennsylvania specializing in semiconductors and cable television equipment. The company was active until 1997, when it split into General Semiconductor (power semiconductors) which was later acquired by Vishay Intertechnology in 2001, 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 Motorola Connected Home Solutions, and was renamed Home and Networks Mobility in 2007. When Motorola split on January 4, 2011, this division became part of Motorola Mobility. On December 19, 2012, ARRIS announced that it would acquire Motorola Mobility's Home unit (the former General Instrument company) from Google for $2.35 billion in cash and stock.[1][2] The acquisition was completed on April 17, 2013.
