The Marconi Company was a British telecommunications and engineering company that did business under that name from 1963 to 1987. Its roots were in the Wireless Telegraph & Signal Company founded by Italian inventor Guglielmo Marconi in 1897, which underwent several changes in name after mergers and acquisitions. The company was a pioneer of wireless long distance communication and mass media broadcasting, eventually becoming one of the UK's most successful manufacturing companies. In 1999, its defence equipment manufacturing division, Marconi Electronic Systems, merged with British Aerospace (BAe) to form BAE Systems. In 2006, financial difficulties led to the collapse of the remaining company, with the bulk of the business acquired by the Swedish telecommunications company, Ericsson.
Marconi Communications, the former telecommunications arm of Britain's General Electric Company plc (GEC), was founded in August 1998 through the amalgamation of GEC Plessey Telecommunications (GPT) with other GEC subsidiaries: Marconi SpA, GEC Hong Kong, and ATC South Africa.
GEC Plessey Telecommunications (GPT) was a British manufacturer of telecommunications equipment, notably the System X telephone exchange. The company was founded in 1988 as a joint venture between GEC and the British electronics, defence and telecommunications company Plessey.

The GPT name ceased to be used in the mid-1990s, and in 1998 the company was amalgamated into Siemens Communications.

TXK was a range of Crossbar exchanges used by the British Post Office telephone network, subsequently BT, between 1964 and 1994. TXC was used as the designation at first, but this was later changed as TXC sounded too much like TXE the code used for later electronic exchanges. Prior to this the GPO had standardised on Strowger for automatic switching and had resisted the adoption of Crossbar, preferring to wait for its electronic switching research to bear fruit. The development of electronic systems however took longer than anticipated and the British equipment manufacturers, particularly Automatic Telephone & Electric (ATE), which later became part of the Plessey group feared that continuing to focus the bulk of their production on Strowger equipment would harm their export sales as Crossbar had already become popular throughout the world.
