Overview
Zenith Electronics is an American electronics company and brand with roots in radio manufacturing and a later specialization in television technology. It began in Chicago in 1918 as Chicago Radio Labs, a small producer of amateur-radio equipment founded by Ralph Matthews and Karl Hassel. Eugene F. McDonald joined the business in 1921, and Zenith Radio Corporation was incorporated in 1923. The name Zenith came from the founders’ amateur-radio call sign, 9ZN, while also suggesting a high point or peak. The company built its reputation through technical innovation and product quality. Zenith introduced an early portable radio in 1924, a mass-produced alternating-current radio in 1926, and push-button tuning in 1927. It expanded into automotive radios during the 1930s and introduced television hardware before the Second World War, although commercial television products reached consumers in 1948. Its product portfolio subsequently included radios, television receivers, phonographs, stereo equipment, picture tubes, hearing-related electronics, government equipment, and other components. The company became especially associated with the Trans-Oceanic shortwave portable radio line, produced from 1942 to 1981, and with innovations in television reception and control. Zenith’s technological influence extended beyond conventional consumer hardware. It experimented with Phonevision, an early subscription-television system, and developed practical wireless television remote controls. Its Space Command system used ultrasonic technology and became one of the company’s best-known inventions. Zenith also helped develop FM multiplex stereo, pioneered television picture-tube designs, and developed the multichannel television sound system used for analog television in the United States and Canada. In the 1990s, it participated in the development of digital high-definition television technology and contributed elements to the Advanced Television Systems Committee, or ATSC, standard. The company’s competitive position weakened as Japanese manufacturers gained share in the American television market. Zenith pursued antitrust and antidumping litigation against Japanese television companies, but the principal claims were ultimately unsuccessful. In an effort to diversify, it acquired Heath Company in 1979 and established Zenith Data Systems. The computer subsidiary became highly profitable and helped support the parent while the consumer business lost money. Zenith sold Zenith Data Systems to Groupe Bull in 1989, partly to raise funds for high-definition television research and reduce debt. Zenith changed its corporate name to Zenith Electronics Corporation in 1984 after leaving the radio business and expanding its interests in computers and cable television. In 1990 it sold a minority stake to GoldStar, the South Korean electronics company that later became LG Electronics, in connection with a technology-sharing arrangement. LG increased its holding to a controlling interest in 1995 and acquired full ownership after Zenith entered Chapter 11 bankruptcy protection in 1999. Existing shareholders’ interests were eliminated in the restructuring. Following the acquisition, Zenith’s former consumer-electronics operations were reduced and integrated into LG’s broader activities. Its profitable Network Systems division, which made cable and satellite television set-top boxes, was sold to Motorola in 2000. LG subsequently marketed selected Zenith-branded televisions and digital television converter boxes in North America. The remaining Zenith organization is primarily described as an LG-owned research and development company concerned with ATSC and digital-rights-management technologies. Thus, Zenith survives as both a historically important American electronics name and a technology-oriented subsidiary, rather than as the independent mass-market television manufacturer it once was.
History
Zenith’s history began in Chicago in 1918, when Ralph Matthews and Karl Hassel established Chicago Radio Labs to make amateur-radio equipment. Eugene F. McDonald joined in 1921, and the business was incorporated as Zenith Radio Corporation in 1923. The Zenith name referred to the founders’ call sign, 9ZN. Early growth came from radio engineering: the company introduced a portable radio in 1924, an alternating-current radio suitable for mass production in 1926, and push-button tuning in 1927. During the 1930s it entered automotive radio production, and it later became a major American producer of home radios, televisions, phonographs, stereo equipment, and electronic components. Zenith introduced its first television set in 1939 and began selling commercial television receivers in 1948. It also established an early FM station in Chicago in 1940. The station later became associated with FM multiplex stereo and transmitted stereo programming in 1961. Zenith’s technical work included high-contrast and flat-face picture tubes, the multichannel television sound system adopted for analog broadcasts in the United States and Canada, and several generations of television receivers. The Trans-Oceanic shortwave radio, manufactured from 1942 through 1981, became one of its most recognizable products. The company was also an important innovator in television services and control systems. Its Phonevision experiments tested subscription television through a telephone-connected descrambler. Zenith first offered a wired television remote control in 1950, followed by Eugene Polley’s Flash-Matic optical remote in 1955. Robert Adler’s ultrasonic Space Command system followed in 1956 and became the company’s signature remote-control technology. Zenith also marketed early home video equipment, including a Sony-built Betamax recorder beginning in 1977. By 1960 Zenith and RCA were the two largest American television manufacturers, each holding more than one-fifth of the domestic market according to the reference material. The company operated extensive Illinois manufacturing and research facilities and employed thousands of workers. However, competition from Japanese manufacturers steadily eroded its television position. In 1970, Zenith joined National Union Electric, Sears, and Motorola in litigation alleging antitrust violations and unlawful dumping by Japanese television manufacturers. The principal claims were dismissed, and appellate proceedings culminated in unfavorable Supreme Court decisions in 1986 and 1987. Zenith sought diversification through the 1979 purchase of Heath Company from Schlumberger for $64.5 million. The resulting Zenith Data Systems computer business performed strongly and became an important source of profits, while Zenith’s consumer operations weakened. The corporation left the radio business in 1982 and changed its name to Zenith Electronics Corporation in 1984. In 1989 it sold Zenith Data Systems to Groupe Bull for $635 million, using the proceeds in part for HDTV research and debt reduction. The remaining business faced increasing financial pressure. In 1990 Zenith sold GoldStar, later LG Electronics, a five-percent interest under a technology-sharing agreement. LG raised its holding to 55 percent in 1995 and ultimately became sole owner after Zenith filed for Chapter 11 bankruptcy in 1999. LG acquired the remaining interest as part of the debt restructuring, leaving prior shareholders without value. Zenith’s Network Systems division, which produced cable and satellite set-top boxes, was sold to Motorola in 2000. LG continued to use the Zenith name selectively, including on digital television converter boxes and some plasma, LCD, and direct-view televisions. The surviving Zenith organization is principally an LG-owned research and development company associated with ATSC and digital-rights-management technologies. The brand’s historical identity therefore combines a once-prominent American consumer-electronics manufacturer with a continuing, narrower technology role inside LG.
