BT Group plc, known simply as BT, is a big company from the UK that works all over the world. It's one of the largest companies that provides phone lines, internet, and mobile services in the UK. BT also offers TV channels and other technology services.
BT's story began a long time ago in 1846 with the Electric Telegraph Company. This was the world's first public company for sending messages by telegraph across the country. Over the years, the company grew and changed. In 1912, the government's General Post Office (GPO) took over most phone services in the UK.
Later, in 1969, the GPO's phone part became Post Office Telecommunications. In 1980, it started using the name British Telecom. It became a private company in 1984, meaning people could buy shares in it. Today, BT is a major player in telecommunications, helping millions of people connect every day.
History of BT
Early Days of Communication
The story of BT starts with electrical telegraphy. This was a way to send messages over long distances using electric signals. From 1846, several private companies in the UK offered these services.
- The Electric Telegraph Company was the first public telegraph company in the world. It built a network across the country.
Government Takes Over
In 1868, the government decided to take control of these telegraph companies. They were put under the General Post Office (GPO). By 1869, the GPO had a monopoly, meaning it was the only company allowed to offer communication services.
When the telephone was invented in 1876 by Alexander Graham Bell, the GPO started offering phone services too. Over time, other private phone companies appeared, but the GPO eventually took over most of them by 1912. This made the GPO the main provider of phone services in the UK.
Becoming Post Office Telecommunications
In 1969, the GPO changed from a government department to a nationalised industry called the Post Office. A new part of this organisation was created called Post Office Telecommunications. This change was made to help the postal and phone services work more efficiently.
The 1970s was a time of big growth for Post Office Telecommunications. They updated many phone exchanges and made it easier to dial directly to other cities and even other countries. They also started developing new digital phone systems.
The Birth of British Telecom
In 1979, the government decided that phone services should be completely separate from the Post Office. The name British Telecom was introduced in 1980. On 1 October 1981, it officially became a state-owned company, independent of the Post Office.
Becoming a Private Company
In 1984, the government decided to sell shares of British Telecom to the public. This process is called privatisation. On 1 April 1984, British Telecommunications became a public limited company (plc). In November 1984, over half of its shares were sold to people and employees. The government sold its remaining shares in 1991 and 1993.
The company changed its main trading name to "BT" on 2 April 1991.
Big Changes and New Services
In the early 2000s, BT faced some financial challenges. To help with this, they sold off some parts of the company. For example, in 2001, their mobile phone business, BT Cellnet, became a separate company called "mmO2" (which later became O2).
BT also started investing a lot in new technologies. In 2006, they began building their "21st Century Network" (21CN), which was a new internet-based network designed to make services faster and more efficient.
Expanding into New Areas
In 2013, BT launched its own television channels, BT Sport, to compete with other broadcasters. They bought rights to show popular sports like the Premier League and UEFA Champions League.
In 2015, BT announced plans to buy EE, a major mobile phone company. This deal was completed in 2016, bringing together BT's home customers with EE's mobile customers. This allowed BT to offer both home internet and mobile services together.
More recently, in 2021, a French company called Altice started buying shares in BT, becoming a significant owner. In 2023, Allison Kirkby was appointed as the new Chief Executive of BT.
What BT Does Today
BT Group is like a parent company for many different businesses. Most of its operations are handled by its main company, British Telecommunications plc. BT is regulated by Ofcom, which makes sure that BT provides fair services and doesn't have too much power in the market.
BT runs the phone lines and internet connections for most homes and businesses in the UK. They are responsible for about 28 million phone lines. BT is also required to provide a fixed phone line to almost any address in the UK and to maintain public payphones.
Besides traditional phone services, BT offers many other products:
- Fast broadband internet
- Mobile phone services
- Digital television services
- Special technology solutions for businesses and governments
BT's Look
In 2019, BT launched a new, simpler logo. In 2022, BT announced that it would focus more on the EE brand for its products for everyday customers.
