The Marconi Company was a British telecommunications and engineering company that technically existed under that rubric from 1963-1987, derived from earlier variations in the name and incorporation, spanning a period from its inception in 1897 until 2006, during which time it underwent numerous changes, mergers and acquisitions. The company was founded by the Italian inventor Guglielmo Marconi and was originally known as The Wireless Telegraph & Signal Company. The company was a pioneer of wireless long distance communication and mass media broadcasting, eventually becoming one of the UKs most successful manufacturing companies. In 1999, its defence manufacturing division, Marconi Electronic Systems, merged with British Aerospace to form BAE Systems. In 2006, extreme financial difficulties led to the collapse of the remaining company, with the bulk of the business acquired by the Swedish telecommunications company, Ericsson.

Marconi's "Wireless Telegraph and Signal Company" was formed on 20 July 1897 after the granting of a British patent for wireless in March of that year. The company opened the world's first radio factory on Hall Street in Chelmsford in 1898 and was responsible for some of the most important advances in radio and television. These include:
- The diode vacuum tube in 1904 (Fleming)
- Transatlantic radio broadcasting
- High frequency tuned broadcasting
- Formation of the British Broadcasting Company (later to become the independent BBC)
- Formation of the Marconi Wireless Telegraph Company of America (assets acquired by RCA in 1920)
- Marconi International Marine Communication Co. (M.I.M.C.Co.), founded 1900 in London
- Compagnie de Télégraphie sans Fil (C.T.S.F.), founded 1900 in the City of Brussels
- Short wave beam broadcasting
In 1900 the company's name was changed to "Marconi's Wireless Telegraph Company" and Marconi's Wireless Telegraph Training College was set up in 1901. The company and factory was moved to New Street Works in 1912, to allow for production expansion in light of the RMS Titanic disaster. Along with private entrepreneurs, Marconi company formed in 1924 the Unione Radiofonica Italiana (URI), which was granted by Mussolini's regime a monopoly of radio broadcasts in 1924. After the war, URI became the RAI, which lives on to this day.
Operations as English Electric subsidiary
English Electric acquired The Marconi Company in 1946 which complemented its other operations; heavy electrical engineering, aircraft and its railway traction business. In 1948 the company was reorganised into four divisions:
These had expanded to 13 manufacturing divisions by 1965 when a further reorganisation took place. The divisions were placed into three groups :
At this time The Marconi Company had facilities at New Street Chelmsford, Baddow, Basildon, Billericay, and Writtle as well as in Wembley, Gateshead and Hackbridge. It also owned Marconi Instruments, Sanders Electronics, Eddystone Radio and Marconi Italiana (based in Genoa, Italy). In 1967 Marconi took over Stratton and Company to form Eddystone Radio.
Expansion in Canada
In 1903 Marconi founded the Marconi's Wireless Telegraph Company of Canada which was later renamed as the Canadian Marconi Company. The radio business of the Canadian Marconi Company is known as Ultra Electronics TCS  since 2002 and its avionic activities as CMC Electronics, owned by Esterline since 2007. 
Expansion as GEC subsidiary
In 1967 or 1968 English Electric was subject to a takeover bid by the Plessey Company but chose instead to accept an offer from GEC. Under UK government pressure, the computer section of GEC, English Electric Leo Marconi (EELM), merged with International Computers and Tabulators (ICT) to form International Computers Limited (ICL). The computer interests of Elliott Automation which specialised in real-time computing were amalgamated with those of Marconi's Automation Division to form Marconi-Elliott Computers, later renamed as GEC Computers. In 1968 Marconi Space and Defence Systems and Marconi Underwater Systems were formed.
The Marconi Company continued as the primary defence subsidiary of GEC, GEC-Marconi. Marconi was renamed GEC-Marconi in 1987. During the period 1968-1999 GEC-Marconi/MES underwent significant expansion.
Acquisitions which were folded into the company and partnerships established include:
- Defence operations of Associated Electrical Industries in 1968, AEI had been acquired in 1967.
- Yarrow Shipbuilders in 1985
- Ferranti defence businesses in 1990
- Ferranti Dynamics in 1992
- Vickers Shipbuilding and Engineering in 1995
- Alenia Marconi Systems in 1998, a defence electronics company and an equal shares joint venture between GEC-Marconi and Finmeccanica's Alenia Difesa.
- Tracor in 1998.
Other acquisitions include:
- Divisions of Plessey in 1989 (others acquired by its partner in the deal, Siemens AG, to meet with regulatory approval).
In a major reorganisation of the company, GEC-Marconi was renamed Marconi Electronic Systems in 1996 and was separated from other non-defence assets.
Marconi name today
GEC, realigning itself as a primarily telecommunications company following the MES sale, retained the Marconi brand and renamed itself Marconi plc. BAE were granted limited rights to continue its use in existing partnerships, however by 2005 no BAE businesses use the Marconi name. Major spending and the dot-com collapse led to a major restructuring of that group, in a debt-for-equity swap shareholders were given 0.5% of the new company, Marconi Corporation plc.
In 1999 Reltec and Fore Systems were acquired at the height of the "dot-com" boom. With its subsequent collapse the Marconi Corporation got into financial difficulties.
In October 2005 the Marconi name and most of the assets were proposed to be bought by the Swedish firm Ericsson. The transaction was completed on 23 January 2006 effective as per 1 January 2006. The Marconi name will still be used as brand within Ericsson. At the time of the acquisition Ericsson announced that they would be rebranding Marconi assets Ericsson and retaining Marconi only as the name of the Italian research facility. However the company has since labeled its OMS line and its Long Haul Digital Radio system Marconi. The rest of the Marconi company was renamed as Telent.
