- Zenith "My Radio" Pendant Transistor Radio, circa 1970 - The size of radios shrank following the advent of transistor technology. Even the smallest vacuum tubes were bulky, and their power consumption ensured the need for large batteries. Transistor radios made of lightweight plastics were cheap and truly portable. With the addition of an earphone a radio such as this allowed the listener to enjoy a completely personal listening experience.

- Transmitter, 1917 - This quenched gap radio transmitter -- a type of spark gap transmitter -- would have transmitted radio waves used for Morse code signals in ship-to-shore communication. Spark gap transmitters, which used an electrical spark to generate radio waves, were the first means of practical radio transmission for the first thirty years of radio development.
