Transistor radio sells for $443 in 1954

the first mass produced transistor radioIn November 1, 1954, the Regency TR-1 transistor radio was the first practical transistor radio made in significant numbers. The initial retail price was $49.95 (roughly $443 in year-2016 dollars) and it sold about 150,000 units.

The look and size of the TR-1 were well received, but reviews of its performance were typically adverse. The Regency TR-1 circuitry was refined from the Texas Instruments prototype, reducing the number of parts, including two expensive transistors. Though this severely reduced the audio output volume, it let I.D.E.A. sell the radio for only a small profit. Read more about it at This Day In Tech History.
