2. Regency TR-1 Transistor (1954)

Built by Texas Instruments and I.D.E.A., this coupled the former’s transistors with the latter’s antenna nous to produce the first widely successful portable radio. Now a design icon, the TR-1 – or, more accurately, its cheaper successors – changed the world by allowing suburban kids to hear the “race” (ie: black) music that became known as rock and roll. Step aside Eddie Izzard: THIS was the first world-famous trannie.
