Transistor radios had been around for a while but it was Sony, a small startup company, and other far-east imports that brought the price down and made “the transistor” a standard part of the baby boomer’s accessories. It weighed a half of a pound, could fit in a pocket, and ran all day on one or two small batteries (the 9 volt was invented to be the same shape as the case). Best of all, they were portable and had tiny earphones, so Rock music could be played without parents listening in.

At the height of their popularity, Sony’s transistor radios went for around $25. That’s the inflation adjusted equivalent of about $200 today, so they weren’t really cheap. By the mid 60s, Hong Kong manufacturers had the price down to about $15. That was still the equivalent of $120 today, so transistor radios became prized posessions.

Along with the portable transistor, car radios took a big step when they moved from vacuum tubes to transistors. Once the tubes were gone, radios came on quickly, and the drain on the battery was a lot less (if you went “parking” with a vacuum tube radio, your battery went dead quickly!).

As compact as they were, early transistor radios were AM only and stereo was a long way in the future. The tuning was a bit fussy, twisting or moving the radio changed the volume and tone, and the analog tuners had trouble holding a station. FM radio broadcasting with its higher frequency response was still a few years off.

New Ways to Listen

Yet, the advent of transistor radios in the 1950s marked a significant shift in the way music was consumed and played a major role in the growth of rock and roll and the development of teen culture. Prior to the introduction of transistor radios, people would typically listen to music on larger, bulky vacuum-tube radios or at home on phonographs. The development of the compact, portable transistor radio allowed teens to carry music with them wherever they went, greatly increasing the accessibility of their rock and roll music.

This fueled the rise of rock and roll and the emergence of teen culture.  The transistor radio became an essential tool for teens to stay connected to their favorite music and to each other. The portability of the radio allowed them to listen to music in a variety of settings, including in their bedrooms, at the beach, and on the go. This gave rise to a new kind of musical culture that was centered around the radio and its ability to bring music to people wherever they were.

The transistor radio also had a profound impact on the way music was marketed and distributed. With the growth of rock and roll, record companies and music industry executives saw the transistor radio as a powerful tool for promoting new music and reaching a wider audience. They started producing smaller, more affordable radios that were specifically designed for teenagers, and they worked to create a more sophisticated marketing and advertising industry around them.  And all of this helped fuel the growth of rock and roll.
