General Instrument

General Instrument (GI) was an American electronics manufacturer based in Horsham, Pennsylvania, specializing in semiconductors and cable television equipment. They formed in New York City in 1923 as an electronics manufacturer. During the 1950s, the company began a series of acquisitions under the direction of Moses Shapiro. Among the more notable purchases was General Transistor in 1960, which led to GI becoming a major producer of transistors, and later, integrated circuits (ICs). By the late 1960s, the company was mostly depending on sales into the television industry, which was further bolstered by the 1967 purchase of Jerrold Electronics.

The company changed markets continually. Through the 1970s they focused mostly on the off-track betting market through their purchase of American Totalisator, but this market faced significant competition in the late 1970s. At this time, GI became well known for their ICs including the CP1600 used in the Mattel Intellivision game console, the AY-3-8910 series of sound chips that were used in a huge variety of designs, and the PIC microcontrollers which remain in production as of 2024^[update]. They also became increasingly active in the cable television field, emerging as the primary supplier in this market by the late 1980s. They sold off their IC division to form Microchip Technology in 1987, leaving them almost entirely dependent on the television market.

GI became a major leader in the development of high definition television. As this market began to saturate, the company split into three parts in 1997; CommScope took the cable infrastructure products, NextLevel the consumer television side, and General Semiconductor the power electronics products. NextLevel took over the GI name the next year. This new GI was purchased by Motorola in 2000, which was in turn purchased by Google who spun out the television side to ARRIS. ARRIS was then purchased by CommScope in 2018, once again bringing together all of GI's original television divisions. General Semiconductor continues to operate separately.

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.

The company initially formed in New York City in 1923 as an electronics manufacturer.

In the 1950s, the company president Moses Shapiro began buying a variety of electronics companies, mostly from the New York area. An early purchase was F. W. Sickles Company, a radio manufacturer, which was fully merged in 1951. In April 1957 they added Radio Receptor Company, in 1959 Harris Transducer, and among their more notable purchases, closed General Transistor in 1960. Most of these were left to operate as wholly owned but independent divisions. The buying continued through the 1960s, added Signalite in 1966 and Universal Controls and American Totalisator in 1967. A more major purchase was Jerrold Electronics in December 1967, which became the company's consumer-facing brand for television-related products, mostly through their cable television products.

1970 saw a series of layoffs and downsizing as the poorly performing parts of the conglomerate began to drag down profits. As part of this, the company's interest in several cable television stations were sold off, mostly through their Jerrold division. As soon as the company's financials improved, the buying spree started anew, buying another five companies by 1975. This had turned them into a $500-million-a-year company, but left them deeply in debt.

Shapiro retired in 1975 and was replaced by Frank Hickey, who focused the company on its two most profitable markets, cable television and gaming. The gaming market was primarily through their purchase of American Totalisator, who ran racetrack systems. GI expanded this into off-track betting and by 1979 they supplied 90% of all the off-track systems in North America.
