English mathematician, Oliver Heaviside, studied the so-called skin effect in telegraph transmission lines. He concluded that wrapping an insular casing around a transmission line both increases the clarity of the signal and improves the durability of the cable. He patented the first coaxial cable in England in 1880.

In 1894, The U.S. Patent office awards renowned inventor, Nikola Tesla, with the first electrical conductor patent. These technologies were the key components necessary to construct the coaxial cables we use today.

The Olympic Games in Berlin in 1936 became the first major event to transmit images via coaxial cables. The closed-circuit transmission ran from the games in Berlin to Leipzig 150 miles away. This event marks the first time large-scale television images were successfully transmitted over an appreciable distance.

Eventually, the most common coax cable became what we now use to connect our televisions and cable modems. These wires are the great-great-grandchildren of the technology developed in the 1880s. However, they still occupy an integral part in our technology and our lives.
