Imagine a time in the world when communication took two weeks via boat (at a minimum, if the weather cooperated) to reach North America from Europe. The Transatlantic Cable resulted in a precipitous drop in transmission delay when on July 27, 1866, the cable connected Valentia Island in Ireland to Heart’s Content in Newfoundland. The process required a tremendous amount of engineering knowledge and was only successful after the 3rd attempt (earlier attempts led to a snapped cable) – the pressure had to be enough to unroll the giant cable, but not so much as to snap the cable. – Daniel Findley, DTC Engineering Economics Instructor
