First edition. Electrons and Holes in Semiconductors with Applications to Transistor Electronics is a book by Nobel Prize winner William Shockley, [1] first published in 1950. . It was a primary source, and was used as the first textbook, for scientists and engineers learning the new field of semiconductors as applied to the development of the transis
An early 2000s transistor radio (Sony Walkman SRF-S84 transistor radio, released 2001, shown without earphones) Rock 'n roll music became popular at the same time as transistor radios. Parents found that purchasing a small transistor radio was a way for children to listen to their music without using the family tube radio.
Regency TR-1 transistor radio. The Regency TR-1 was the first commercially manufactured transistor radio, introduced in 1954. Despite mediocre performance, about 150,000 units were sold, due to the novelty of its small size and portability.
James Ernest Smith, founder of the National Radio Institute. The National Radio School was established in 1914 in Washington, D.C., by James Ernest Smith (1881–1973) and Emanuel R. Haas (1891–1947). 1 Smith was a teacher at McKinley Manual Training School (which was moved in 1926 to its final location now known as McKinley Technology High School).
Born in 1907 in Houston, Texas, Turner began working with crystal diodes at age 15 and published his first article on radio electronics at age 17. [1] He attended Armstrong Tech in Washington, D.C. [2] In 1925, still a teenager, he built what was then the world's smallest radio set, and was awarded the second commercial radio operator's license in the third district. [2]

The all-transistor car radio was a $150 option. [51] [52] [53] The Sony TR-63, released in 1957, was the first mass-produced transistor radio, leading to the mass-market penetration of transistor radios. [54] The TR-63 went on to sell seven million units worldwide by the mid-1960s. [55]
The ZN414 was popular amongst hobbyists, as a fully working AM radio could be made with just a few external components, a crystal earpiece and a 1.5 V cell. The original ZN414 chip from Ferranti was supplied in a 3-pin, metal TO-18 'transistor' package, whereas the GEC part and later Ferranti ones (ZN414Z) used the plastic TO-92 encapsulation.
