Nippon Telegraph and Telephone Corporation (abbreviated as NTT) was established in 1976 as a wholly owned subsidiary of Japan's largest telecommunications service provider, Nippon Telegraph and Telephone Corporation. The company has grown rapidly thanks to its success in relying on the NTT Research Institute and its technology transfer of its research results.
On 6 June 2017, the BrandZ Top 100 Most Valuable Global Brands 2017 was announced and Nippon Telegraph and Telephone was ranked 50th. On 19 July 2018, the Fortune 500 list was released and Nippon Telegraph and Telephone was ranked 55th. Nippon Telegraph and Telephone Corporation is ranked 126th in the 2018 World's Top 500 Brands list.
Nippon Telegraph and Telephone Corporation (NTT) is the largest telecommunications network operator in Japan. It is the world's largest telecommunications company in terms of assets and revenue. NTT, formerly Nippon Telegraph and Telephone Corporation (NTT), has improved its telecommunications services by strengthening its operations and improving its facilities over the past 12 years since its privatisation in 1985, and has introduced a variety of high-quality services to create a more convenient and faster information and communications environment for its customers.
Nippon Telegraph and Telephone includes East Nippon Telegraph and Telephone Corporation, West Nippon Telegraph and Telephone Corporation, Nippon Telegraph and Telephone Communications Corporation, Nippon Telegraph and Telephone Data Corporation, Nippon Telegraph and Telephone DoCoMo Corporation and others. It is also an organisation that creates integrated value and participates in research and development, thereby enabling group companies to provide a wide range of information dissemination services. Research covers a wide range of activities from scientific and technological research to commercialisation, including communication networks, service platforms, media processing and generally photonic equipment.
Nippon Telegraph and Telephone (NTT), the world's number one telecommunications company, has completed a US Telegraph and Telephone style spin-off, splitting into two parts, Local Signal and Long Distance Services. Unlike Ma Bell's gang, however, the two parts of the split remained closely linked, and NTT became the holding company for both. NTT East and NTT West, the regional telecoms operators, had a monopoly on the regional telecoms business, while NTT Long Distance faced growing competition. ntT was also the leader in the ISP business. ntT DoCoMo, a telecoms operating company with a focus on mobile phone business, captured 63% of the mobile phone business market in Japan. ntT also operated international investment business through NTT also operates international investment businesses through Pacific Rim. 46% of NTT's shares are held by the state.
In 1997, the Japanese government amended the Telecommunications Act to allow the NTT Group to develop its business in the international telecommunications market, and the NTT Group is launching a number of international value-added services under the brand name "Arcstar".
On 3 December 2004, NTT Communications Corporation (a large telecom operator within the NTT Group engaged in domestic long-distance and international communications in Japan) and Beijing NewNet Internet Technology Co Ltd signed a cooperation agreement in Guangzhou on "Overseas Virtual Private Hosting Service" to capture the high-end user market for web hosting in China, mainly to attack the value-added telecom market. NTT Mobile Communications said on 27 December 2004 that it would acquire shares in two holding companies with information services subsidiaries in China for a total of US$8.2 million (US$4 million in Emcore Technology Inc. and US$4.2 million in Digital MediaGroup Co. Co.) to provide wireless telecommunication services to the fast-growing China.
The information and communications industry is at a turning point in its history, where multimedia and globalisation will cause fundamental changes in three key areas.
The first is in the area of communications services. When NTT completed its digital network, NTT did its utmost to ensure maximum availability of all forms of services at competitive prices. Although NTT's telephony services are already at an internationally advanced level, NTT will continue to improve them by offering such things as virtual private communications networks and discounted call rates. In the multimedia field, Open Computer Network (OCN) is a new communications service for computer communications. Meanwhile, the Integrated Services Digital Network (ISDN) will continue to grow exceptionally fast. The growth of these services will enable NTT's network business to grow alongside NTT's telephone business in the near future.
The second major change will be the reorganisation and reallocation of NTT's resources. The digital network has led to significant changes in infrastructure, and NTT will therefore aim to reorganise its human, material and financial resources. In order to open up new businesses, miniaturise groups and reduce costs, NTT places a very high priority on pursuing technological advances. In terms of investment in equipment and facilities, NTT is focusing on introducing fibre optics into the access network and considering the use of mobile phones, Personal Handy Phone Systems (PHS) and other wireless communications equipment to enhance the operational performance of the network. NTT will also reallocate and train its human resources to respond more effectively to these changes.
The third major change will be in the strategic use of resources, and NTT's immediate priority should be to maximise the use of NTT's human and material resources. Therefore, NTT will increase the openness of its network, implement a global strategy within NTT and establish a decentralised, cluster-based organisation. In this coming era, no company or country can go it alone; they will have to cooperate and of course compete with each other.
