The Communications Act 2003 is an Act of the Parliament of the United Kingdom. The act, which came into force on 25 July 2003, superseded the Telecommunications Act 1984. The new act was the responsibility of Culture Secretary Tessa Jowell. It consolidated the telecommunication and broadcasting regulators in the UK, introducing the Office of Communications (Ofcom) as the new industry regulator. On 28 December 2003 Ofcom gained its full regulatory powers, inheriting the duties of the Office of Telecommunications (Oftel). Among other measures, the act introduced legal recognition of community radio and paved the way for full-time community radio services in the UK, as well as controversially lifting many restrictions on cross-media ownership. It also made it illegal to use other people's Wi-Fi broadband connections without their permission. In addition, the legislation also allowed for the first time non-European entities to wholly own a British television company.

The Cooke and Wheatstone telegraph was an early electrical telegraph system dating from the 1830s invented by English inventor William Fothergill Cooke and English scientist Charles Wheatstone. It was a form of needle telegraph, and the first telegraph system to be put into commercial service. The receiver consisted of a number of needles which could be moved by electromagnetic coils to point to letters on a board. This feature was liked by early users who were unwilling to learn codes, and employers who did not want to invest in staff training.

In the nineteenth century, the United Kingdom had the world's first commercial telegraph company. British telegraphy dominated international telecommunications well into the twentieth. Telegraphy is the sending of textual messages by human operators using symbolic codes. Electrical telegraphy uses conducting wires to send messages, often incorporating a telegram service to deliver the telegraphed communication from the telegraph office. This is distinct from optical telegraphy that preceded it and the radiotelegraphy that followed. Though Francis Ronalds first demonstrated a working telegraph over a substantial distance in 1816, he was unable to put it into practical use. Starting in 1836, William Fothergill Cooke, with the scientific assistance of Charles Wheatstone, developed the Cooke and Wheatstone telegraph. The needle telegraph instrument suggested by Wheatstone, the battery invented by John Frederic Daniell, and the relay invented by Edward Davy were important components of this system.

The Faraday Building is a building in the City of London. Because of its location, the building is a prominent feature of the London skyline despite being only 11 storeys high.

Gustav Siegfried Eins (GS1) was a British black propaganda radio station during World War II operated by the Political Warfare Executive (PWE). It was the brainchild of Sefton Delmer, a former BBC German service announcer recruited by PWE in 1940, and claimed to be an illegal radio station operating within Nazi Germany. The callsign was based on the German Army phonetic alphabet for the letters GS, but had no meaning.

It is generally recognized that the first radio transmission was made from a temporary station set up by Guglielmo Marconi in 1895 on the Isle of Wight. This followed on from pioneering work in the field by a number of people including Alessandro Volta, André-Marie Ampère, Georg Ohm and James Clerk Maxwell.

The Imperial Wireless Chain was a strategic international communications network of powerful long range radiotelegraphy stations, created by the British government to link the countries of the British Empire. The stations exchanged commercial and diplomatic text message traffic transmitted at high speed by Morse code using paper tape machines. Although the idea was conceived prior to World War I, the United Kingdom was the last of the world's great powers to implement an operational system. The first link in the chain, between Leafield in Oxfordshire and Cairo, Egypt, eventually opened on 24 April 1922, with the final link, between Australia and Canada, opening on 16 June 1928.

Post Office Telecommunications was set up as a separate department of the UK Post Office, in October 1969. The Post Office Act of that year was passed to provide for greater efficiency in post and telephone services; rather than run a range of services, each organisation would be able to focus on their respective service, with dedicated management. By law, the Post Office had the exclusive right to operate the UK national telecom network, and limited ability to license other providers' services and equipment. The National Telephone Company controlled most of telephony in Britain before the 1880 ruling on the 1869 Telegraph Act mandated a nationalised service – which was instated in 1911. The 1869 Telegraph Act granted this monopoly over communications and it was confirmed in 1880 that this Act included telephony even though the telephone had not been invented when the Act was first conceived. Post Office engineers in the inter-war period had considerable expertise in both telecommunications and hearing assistive devices.

Taplow Court is a Victorian house in the village of Taplow in Buckinghamshire, England. Its origins are an Elizabethan manor house, remodelled in the early 17th century. In the 18th century the court was owned by the Earls of Orkney. In the 1850s, the court was sold to Charles Pascoe Grenfell, whose descendants retained ownership until after the Second World War. The court then served as a corporate headquarters for BT and subsequently for Plessey Electronics. In 1988 it was bought by the Buddhist foundation, Soka Gakkai International and serves as their UK headquarters.

Two cables were laid between 1955 and 1956 with one cable for each direction. It was inaugurated on September 25, 1956. The cable was able to carry 35 simultaneous telephone calls. A 36th channel was used to carry up to 22 telegraph lines.

The Telecommunications Research Establishment (TRE) was the main United Kingdom research and development organization for radio navigation, radar, infra-red detection for heat seeking missiles, and related work for the Royal Air Force (RAF) during World War II and the years that followed. It was regarded as "the most brilliant and successful of the English wartime research establishments" under "Rowe, who saw more of the English scientific choices between 1935 and 1945 than any single man."

Viewdata is a Videotex implementation. It is a type of information retrieval service in which a subscriber can access a remote database via a common carrier channel, request data and receive requested data on a video display over a separate channel. Samuel Fedida, who had the idea for Viewdata in 1968, was credited as inventor of the system. The first prototype became operational in 1974. The access, request and reception are usually via common carrier broadcast channels. This is in contrast with teletext.
