Communication cables laid on the ocean floor were not created when the Internet came along. The first “submarine cable” was dropped into the water in 1858, but only lasted about three weeks. It was attempted again in 1866, and worked, sending telegraph signals across the Atlantic. Telephone communications (i.e., AT&T) used underwater cables beginning in 1956 and the Internet started utilizing them in 1988.
