By the 1970s and 1980s, the Walkman (see entry under 1970s- Music in volume 4) essentially replaced the transistor radio, due to its superior sound quality and ability to play cassette tapes.įitch, Richard D.

Japanese manufacturer Sony exported its TR-63 transistor radio to the United States starting in 1957. It could be used instead of the bulkier vacuum tubes to control the signals that sent radio (see entry under 1920s-TV and Radio in volume 2) broadcasts through the air. A transistor is a small device, about the size of a pencil eraser, that generates and amplifies electric signals. The invention of the transistor in the early 1950s paved the way for a mass-produced pocket radio. The magazine Popular Mechanics had published instructions for building a do-it-yourself pocket radio, using a wooden glove box for the body, in 1925. The first transistor radio (the Regency TR-1) was produced by Regency Electronics in cooperation with Texas Instruments in 1954.
