Our History

BT is the world's oldest communications company, with a direct line of descent from the world's first national telecommunications undertaking. The Electric Telegraph Company incorporated in 1846, was the first to develop a nationwide communications network. Within 10 years an international network had been developed, making communications possible within minutes and hours instead of days and weeks.

Fast forward to today and technology is more central to BT's business than ever, as it builds on the foundation of the digital era to create the information age.

As guardian of the UK’s telecommunications legacy we recognise and attach great value and importance to our long and rich heritage. Our Heritage Policy details how, as a socially responsible company, we ensure the long-term preservation of this national heritage while providing access to the widest possible audience.
