Boing Boing’s iPod, circa 1954 points to a BBC story, The Old New, about a once-novel transistor radio that bears an uncanny resemblance to the iPod Mini:
The Regency TR-1 transistor radio, made in 1954, had a decent claim to be a genuine piece of innovation, however. It was, by popular agreement, the world’s first commercially sold transistor pocket radio.Small enough to hold in your hand, and powered by batteries, it came in a variety of delicious colours, including green, pearlescent blue, lavender, white and red.
The device went on sale just in time for hip young gadget freaks to hear Elvis Presley singing That’s All Right — recognised by many as the moment at which rock’n'roll was born.
The TR-1 was marketed under the slogan “See it! Hear it! Get it!”
