Beginning with a great example of a thrift store find, the Storyteller radio device has all the elements of a curiosity-sparking find. It’s housed in a sturdy metal case with many switches, labels, and red lights. Therefore, it resembles an important piece of professional-quality radio equipment from the 1970s or 1980s; actually, this vintage promotional radio device truly is a relic from that era. Indeed, it was.
The Storyteller was produced by Tri-Fi Promotions. Probably been created as a recording and transmission package for promotional purposes. It allowed users to record messages and then transmit the same message through a short-range radio frequency to other radios that had received the signal.
Designed to Deliver a Single Message
The design of the front panel of the Storyteller is revealing. The XMTR switch allows the unit to act as a transmitter. With Rec’d / Play set, the unit can be used to record audio. Then flip the unit into the playback mode. The Start/Stop buttons are responsible for playing and stopping the message. Along the top row of the unit there are several lines of red lights. They indicate record levels and elapsed time to help the operator monitor the audio. For example, how long the unit has been playing. As a promotional radio device from a vintage era, its features made it unique.
This type of simple design lends itself perfectly to creating looping promotional announcements. For example, a business could create a short announcement about why they think they’re better than their competitors, or a person who owns property could create a “talking house” sign that describes his properties. Businesses selling cars could create an announcement to describe each car on sale. In many cases, using a vintage promotional radio device like the Storyteller allowed businesses to deliver messages in a memorable way.
Use Cases for the Storyteller
Devices like the Storyteller were probably used anywhere a spoken message could catch people’s attention. Real estate agents, for example, could have used a unit like this on house signs to broadcast details about the property. Including whether it was for sale and how much it cost. Dealerships selling cars could have used them to tell listeners about the features of their cars on display. Local businesses may have used similar units to run simple voice ads and promote themselves to people nearby. Such a promotional radio device, especially one that now feels vintage, provided a distinct advantage for marketers.
Visualizing a Sign
It is relatively easy to imagine a sign saying something like, “Tune in to hear the story.” That sounds quaint and old-fashioned today, but when it was first conceived, it was a good way to combine radio, advertising, and recorded sound. This illustrates how a vintage promotional radio device could help bridge creativity and technology for unique advertising.
