The first commercial device to use a transistor was the Sonotone 1010 hearing aid, created in 1953. The first transistor radio, the Regency TR-1, went on the market for $49.99 in 1954.

Texas Instruments beat them to market with a transistor radio, the Regency TR-1, in 1954, but in 1955, Sony produced the TR-55. Of the five transistors inside, some were alloyed transistors, and ...

A working sandwich transistor would require that electricity travel straight across a crystal instead of around the surface. But Bardeen 's theory about how the point-contact transistor worked ...
