Over 95% of international data and voice call traffic travels through nearly a million miles of underwater communication cables.
These cables carry government communications, financial transactions, email, video calls and streaming around the world.
The first commercial telecommunication subsea cable was used for telegraphs and was laid across the English Channel between Dover, England and Calais, France in 1850.
The technology then evolved to coaxial cables that carried telephone conversations, and most recently, fiber optics that ferry data and the internet as we know it.
