- Ceramic Insulator, 1880-1920 - Insulators--made of poor electrical conductors such as glass, ceramic, plastic, or composite materials--help make electric power and communication transmission lines safe. They isolate wires from utility poles, transmission towers, and buildings--structures that are made of conductive materials that could cause signal degradation, power loss, fire, or pose a shock hazard if the lines touched them.

- 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.

- Princess Telephone, Model 701B, 1959-1963 - The Princess telephone was designed by Henry Dreyfuss in 1959. It's a great example of the transition of the telephone from a strictly utilitarian device to a fashionable home accessory for middle class America. Compact and featuring a backlit dial, it was originally marketed to women as a bedroom phone; the slogan was, "It's little...It's lovely...It lights." It stayed in production from 1959-1994.
