Many thanks to SWLing Post contributor, Bill Tilford, who shares the following:

Today is the anniversary of the announcement of the first commercially available transistor radio, the Regency TR1, in 1954. It wasn’t very good, but it started something.

You can tell something about the frequency allocations of the time by how the numbers are spaced.

To put the ad below in context, the median weekly family income in 1954 was about $81.00.

Thank you for sharing this, Bill! If you’d like to read more about the TR1 and view a wide variety of product photos, check out this dedicated TR1 website.

I’m curious if any Post readers own a Regency TR1. Please comment!
