- Radio for All, 1922 - Hugo Gernsback was the publisher of the first science fiction and radio electronics magazines. His 1922 book "Radio for All" is an accessible primer on radio history and operation. In it, he also imagined a holistic, technology-driven future where radio waves controlled aircraft and autonomous ships, delivered newspapers, acted as telemedicine and radiotelephone portals -- and even powered roller skates!

- Antenna Insulator, 1920-1940 - 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.

- Telephone Switchboard, circa 1905 - Before long-distance direct dialing became widespread in the 1960s, callers relied on switchboards to connect calls. When a caller picked up the phone, a switchboard operator on the line would ask them for the number they would like to connect to. The operator would put the call through by manually connecting the caller's line to the appropriate recipient via the switchboard.
