The British Thomson-Houston Co. Ltd., (BTH) was created as a subsidiary of the General Electric Company, USA in 1896 to exploit the sale of products in the United Kingdom. BTH was a reconstruction of an existing firm, Laing, Wharton and Down (1886). The BTH manufacturing works were based at Rugby, Warwickshire and the company’s products included induction motors, alternators, switchgear, turbo-generators and turbines, as well as a large number of rotary converters and motor converters, primarily for chemical plants.
During the First World War, BTH’s most significant contribution was the development of marine apparatus for the naval service. The 1920s saw a period of vast expansion for the company with new extensions built at many of its factories such as Willesden, Birmingham, Chesterfield and Lutterworth. BTH amalgamated with Metropolitan-Vickers Electrical Company Ltd to form Associated Electrical Industries (AEI) in 1928 although both companies retained their separate identities and continued to compete for the same contracts.
BTH developed manufactured electric torpedoes and electrical components for aircraft engines, munitions, etc., during the Second World War and in 1935 independently of each other, BTH and Metropolitan-Vickers were the first two companies in the world to construct jet engines.

General Electric Company, USA (GE), was incorporated on 15 April 1892 as a result of a merger between competing companies Edison General Electric and the Thomson-Houston Company, based in Schenectady, New York. In 1896 GE established a subsidiary company called British Thomson-Houston (BTH) for the exploitation of its products in the United Kingdom. In the railway field GE produced electric propulsion equipment, electric locomotives and diesel-electric locomotives from the 1930s and also supplied electrical equipment for PCC streetcars. In 1989 GE agreed to combine its European business interests in appliances, medical systems, electrical distribution, and power systems with the formerly unrelated British corporation General Electric Company.
GE’s business groups in the early 21st century were in the areas of commercial finance; consumer finance; infrastructure (including diesel locomotives, jet engines, water treatment systems, and energy delivery systems such as power grids); consumer and industrial technologies (including appliances and lighting products); health care (including diagnostic and imaging products); and media and entertainment through NBC Universal. In 2009 it was announced that GE had agreed to sell a majority stake in NBC Universal to Comcast. In June 2014 GE bought Alstom’s Power and Grid businesses.
