The future began 75 years ago this week with the invention of the transistor. We’ve been looking at the ecosystems of innovation that grew the transistor into the interconnected, digital revolution.

Texas Instruments and Industrial Development Engineering Associates (I.D.E.A.) announce the first transistor radio, the Regency TR-1, which sold for $49.95 (about $440 in today’s dollars). 50 ...

In the spring of 1954, Texas Instruments had designed and built a prototype and was looking for an established radio manufacturer to develop and market a radio using its transistors. None of the major ...

Roger Robinson Webster led the Texas Instruments team that developed the pocket-size transistor radio, the commercial product that ushered in the digital age in 1954. A wizard who built a 1-inch ...

Tube radios were just way too big and heavy to fit in your pocket. But the people at Regency based their radio on a product from a company called Texas Instruments — the transistor.

For that was the day Texas Instruments and a company called I.D.E.A. jointly unveiled the TR-1 ... the very first transistor radio.

As you’d expect, a transistor radio heading toward its 70th birthday requires a little care to return to its former glory, and while this one is very quiet it does at least work after a fashion.

Fortune magazine declared 1953 the “Year of the Transistor,” and, by 1954, Texas Instruments had introduced the transistor radio.

According to a recent IEEE article, a transistor cost about $8 in today’s money back in the 1960’s. Consider the Regency TR-1, the first transistor radio from TI and IDEA.

The first transistor radio to make it to market wasn’t GE’s, but the Regency TR-1, built with Texas Instrument parts. GE’s Model 678 hit shelves a few months later.

TI had announced its own TRF6150 direct-conversion radio in time for last month's GSM World Congress. Bill Krenik, advanced architecture director at TI's wireless business unit, said ParkerVision's ...
