Rumsfeld. He sold off several divisions to cut overhead. The company then began investing heavily in the emerging high definition television (HDTV) market. To continue operations they laid off large numbers of staff, mostly at the headquarters. In 1992 they demonstrated their HDTV system and won a contract for 100,000 compressors. This led Rumsfeld to launch an initial public offering in 1993, after which he left the company in August. Breakup The HDTV market stabilized the company for a time, but by the mid-90s other entrants were once again eroding the company's profits. In 1997 the company split into three parts, General Semiconductor (power electronics), CommScope (cable infrastructure) and NextLevel Systems (cable and satellite systems). NextLevel took over the GI name in February 1998. The "new" GI was purchased by Motorola in January 2000 for $17 billion and became the new Broadband Communication Sector (BCS) along with an acquisition of Zenith Network Systems a few months later. NextLevel Systems, the former GI cable and satellite TV division, took over the General Instrument name in February 1998. The new (post-split) GI Corporation was acquired by Motorola in January 2000 for $17 billion and became the new Broadband Communication Sector (BCS) along with an acquisition of Zenith Network Systems a few months later. After being called Connected Home Solutions, it 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. The acquisition was completed on April 17, 2013. On November 8, 2018, CommScope announced that it would acquire ARRIS in a cash deal valued at $7.4 billion including the repayment of debt. This acquisition brings back together two of the former General Instrument companies from the 1997 split. Moses Shapiro, father of former Monsanto head Robert B. Shapiro, was Chairman from 1969 to 1975. Frank G. Hickey served as chief executive officer from 1975 to 1990, as did Donald Rumsfeld from 1990 to 1993.
