- Transoceanic Voice Cables, circa 1956 - The opening of the TAT-1 (Transatlantic No. 1) cable in 1956 made it possible to place long-distance telephone calls across the Atlantic Ocean. Until this cable was installed, voice transmission over long distances occurred through an unreliable and expensive radio relay system. The TAT-1 responded to an increased demand for instant communication, establishing the first accessible international telephone service.
