BT Group plc, trading as BT, is a holding company which owns British Telecommunications plc,〔(【引用サイトリンク】url=http://www.btplc.com/Thegroup/Ourcompany/Groupbusinesses/index.htm )〕 a British multinational telecommunications services company with head offices in London, United Kingdom. It has operations in around 170 countries. BT's origins date back to the founding of the Electric Telegraph Company in 1846 which developed a nationwide communications network. In 1912, the General Post Office, a government department, became the monopoly telecoms supplier in GB. The Post Office Act of 1969 led to the GPO becoming a public corporation. British Telecommunications, trading as British Telecom, was formed in 1980, and became independent of the Post Office in 1981. British Telecommunications was privatised in 1984, becoming British Telecommunications plc, with some 50 percent of its shares sold to investors. The Government sold its remaining stake in further share sales in 1991 and 1993. BT has a primary listing on the London Stock Exchange, a secondary listing on the New York Stock Exchange, and is a constituent of the FTSE 100 Index. BT controls a number of large subsidiaries. BT Global Services division supplies telecoms services to corporate and government customers worldwide, and its BT Consumer division supplies telephony, broadband, and subscription television services in Great Britain to around 18 million customers.〔(【引用サイトリンク】title=BT Consumer )〕 In February 2015, BT announced an agreement to purchase the British mobile phone network EE Limited for £12.5bn, subject to regulatory approval.〔(【引用サイトリンク】title=BBC News - BT to buy mobile firm EE for £12.5bn )〕 Most of BT's profits are generated by its Openreach subsidiary, which controls the UK's 'last mile' copper infrastructure. Since 2005, BT have been accused of abusing their control of Openreach, particularly by underinvesting in the UK's broadband infrastructure, charging high prices and providing poor customer service. The UK's telecoms regulator Ofcom is currently investigating whether to order BT to sell Openreach, and is expected to report in January 2016.〔 ==History== BT's origins date back to the establishment of the first telecommunications companies in Britain. Among them was the first commercial telegraph service, the Electric Telegraph Company, established in 1846. As these companies amalgamated and were taken over or collapsed, the remaining companies were transferred to state control under the Post Office in 1912. These companies were merged and rebranded as British Telecom. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「BT Group」の詳細全文を読む スポンサード リンク
