Mercury Communications was a national telephone company in the United Kingdom, formed in 1981 as a subsidiary of Cable & Wireless, to challenge the then-monopoly of British Telecom (BT). Although it proved only moderately successful at challenging BT's dominance, it led the way for new communication companies to attempt the same.

Northwestern Bell Telephone Company is an American communications provider that serves the states of the upper Midwest opposite the Southwestern Bell area, including Iowa, Minnesota, South Dakota, North Dakota, and Nebraska. As of 1991 the name Northwestern Bell is no longer the corporate identity, although Northwestern Bell is now owned by the Lumen Technologies and is therefore doing business as Lumen. Doing business as names were not begun before 2001; that is why the Northwestern Bell name was dormant but later revived by CenturyLink.

The British Telecom microwave network was a network of point-to-point microwave radio links in the United Kingdom, operated at first by the General Post Office, and subsequently by its successor BT plc. From the late 1950s to the 1980s it provided a large part of BT's trunk communications capacity, and carried telephone, television and radar signals and digital data, both civil and military. Its use of line-of-sight microwave transmission was particularly important during the Cold War for its resilience against nuclear attack. It was rendered obsolete, at least for normal civilian purposes, by the installation of a national optical fibre communication network with considerably higher reliability and vastly greater capacity.
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.

Established in England in the 17th century, the GPO was a state monopoly covering the dispatch of items from a specific sender to a specific receiver ; it was overseen by a Government minister, the Postmaster General. Over time its remit was extended to Scotland and Ireland, and across parts of the British Empire.
The Telephone Cases, 126 U.S. 1 (1888), were a series of U.S. court cases in the 1870s and the 1880s related to the invention of the telephone, which culminated in an 1888 decision of the U.S. Supreme Court that upheld the priority of the patents belonging to Alexander Graham Bell. Those patents were used by the American Bell Telephone Company and the Bell System, although they had also acquired critical microphone patents from Emile Berliner.
The Cities of Manchester and Salford and some surrounding urban areas such as Stockport, Oldham and Bolton,, were the location of several advances in the development of telephony in the United Kingdom. A Manchester company installed the country's first regular telephone system in the city, wiring solutions which were adopted across Britain were initiated in Manchester and Stockport, the city was (arguably) the site of the UK's first telephone exchange and a service which was the forerunner of modern mobile phones was controlled from the city.
