Overview
Thorn Electrical Industries was a major British electrical engineering and consumer-products group whose activities ranged from lamps and lighting systems to radios, televisions, domestic appliances, industrial electronics, and rental services. Its origins lay in the Electric Lamp Service Company, established in Britain in 1926 by the Austrian-born businessman Jules Thorn after he remained in the country following the bankruptcy of his former employer. The business was incorporated in 1928 and expanded from electrical-goods dealing into manufacturing after Thorn acquired control of the Chorlton Metal Company and the Atlas Lamp Works in 1932. Production of lamps began at Edmonton in north London, creating the foundation for what became one of the company’s most important businesses. The group broadened rapidly during the 1930s and 1940s. It distributed Ferguson radios, acquired Ferguson Radio Corporation in 1946, and established DER in 1939 to manufacture and distribute televisions and other domestic products. By 1948 it employed approximately 2,400 people across factories in England and Wales and produced lamps, fluorescent fittings, radios, television receivers, and household appliances. Its consumer businesses were supported by retail, servicing, and rental operations, allowing Thorn to participate in both manufacturing and the distribution of electrical goods. Expansion accelerated in the 1950s and 1960s through licensing agreements, joint ventures, and acquisitions. Thorn worked with Sylvania on fluorescent-lamp development, entered an arrangement with Bendix Aviation to manufacture electrical components for guided missiles and supersonic aircraft, and produced HMV and Marconiphone equipment under agreement with EMI. It also acquired Philco’s British interests, Tricity Cookers, Moffat’s UK interests, Metal Industries, and other electrical and electronic businesses. Consumer electronics operations incorporated the Ultra brand, while lighting was marketed through names including Atlas, Mazda, and Ekco. Domestic appliances included Tricity, Main, and Moffat products, alongside refrigerators, gas fires, and small electrical goods. The 1968 acquisition of Radio Rentals was a major strategic step. Its rental activities were combined with Domestic Electrical Rentals, creating Britain’s largest television-rental group at the time, with millions of subscribers and a nationwide store network. Thorn also acquired Kenwood Manufacturing through a hostile takeover, strengthening its position in domestic appliances. By the end of the 1960s the group operated more than 50 major factories in Britain and eight overseas plants, with businesses covering lighting, television, radio, recording equipment, appliances, industrial catering, electronic components, control equipment, and fire protection. In 1979 Thorn merged with EMI Group to create Thorn EMI. The combined company operated for nearly two decades, but its electronics and rental interests were eventually separated. Shareholders approved the demerger of Thorn in 1996, after which the electronics and rental businesses operated as Thorn plc. In 1998 Future Rentals, a subsidiary of Nomura Group, agreed to acquire the company for £980 million. Thorn was subsequently transferred to Terra Firma Capital Partners, which established the BrightHouse retail chain and reorganized the remaining operations. The remainder of the business was sold to a private buyer in 2007. A later Thorn venture, the Australian online retailer Big Brown Box, was launched in 2008 and sold to Appliances Online in 2011. Thorn Electrical Industries therefore survives primarily through the history and successor ownership of its former businesses and brands rather than as an independent operating company.
History
Thorn Electrical Industries developed from Jules Thorn’s Electric Lamp Service Company, founded in Britain in 1926 after Thorn, an Austrian immigrant, established himself as a dealer in electrical and radio goods. The company was incorporated in 1928. Thorn added manufacturing capability through the acquisition of Atlas Lamp Works in 1932, beginning lamp production at Edmonton, and later expanded into radio and television. Lotus Radio was formed in 1933, while the company became Thorn Electrical Industries Limited in 1936 and became publicly listed that year. Thorn’s relationship with Ferguson Radio Corporation began with distribution in 1936 and culminated in Thorn’s acquisition of Ferguson in 1946. In 1939 Thorn created DER to pursue television manufacturing and rental-related activities. Postwar growth brought factories and operations producing lamps, fluorescent fittings, radios, televisions, and domestic appliances. Agreements with Sylvania, Bendix, and EMI during the 1950s extended its technical and manufacturing reach. Thorn also acquired Philco’s British interests and Tricity Cookers. The 1960s transformed Thorn into a diversified electrical conglomerate. Ultra Electronics’ consumer interests were integrated into the group, lighting activities were combined with Associated Electrical Industries in British Lighting Industries, and acquisitions added Glover and Main, Moffat, Metal Industries, and Kenwood. Thorn’s brands included Ferguson, Ultra, HMV, Marconiphone, Atlas, Mazda, Ekco, Tricity, Main, and Moffat. Its operations covered lighting, household appliances, television and radio, recording equipment, industrial catering, control and instrumentation, electronic valves, television tubes, and defense-related component manufacturing. The purchase of Radio Rentals in 1968 was particularly significant. The business was combined with Domestic Electrical Rentals and became the leading British television-rental operation, supported by a large subscriber base and extensive retail network. Thorn’s scale at the time included more than 50 British factories and eight overseas plants. The group also had relationships with major international companies, including Bendix, Sylvania, EMI, and General Telephone and Electronics. Thorn merged with EMI in 1979. The resulting Thorn EMI group later sought to restructure and dispose of its electronics operations. In 1996 shareholders approved a demerger, restoring Thorn as a separately listed company. Nomura’s Future Rentals agreed to acquire Thorn in 1998, and ownership later passed to Terra Firma Capital Partners. The remaining businesses were reorganized and progressively sold, including the disposal of the remainder of Thorn in 2007. Thorn also launched Big Brown Box in Australia in 2008, but the online retailer was sold in 2011. The original Thorn Electrical Industries entity is now historical rather than an independent active company.
