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.
The success of transistor radios led to transistors replacing vacuum tubes as the dominant electronic technology in the late 1950s. [28] The transistor radio went on to become the most popular electronic communication device of the 1960s and 1970s. Billions of transistor radios are estimated to have been sold worldwide between the 1950s and ...
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]
In the 1960s, company best seller products became transistor radio receivers. One of the most famous was the Koliber model. In 1969, three- band receiver models were available ( Dominika and Izabella ), as previous radios could only receive two bands, low frequency and medium wave , and a year later the Laura 4-band receiver came into production.
This made Sony the first company to produce commercial transistor radios from the ground up. American company Regency had launched their Regency TR-1 transistor radio earlier in 1954, but bought the transistors from Texas Instruments. Printed circuit boards were used, which was unusual for the time. [6] [8] [3]

The October 1955 issue of Radio & Television News magazine (page 41) printed a full-page, detailed article, on Philco's new consumer phonograph. The Philco all-transistor portable phonograph TPA-1 and TPA-2 models played only 45rpm records and used four 1.5v "D" batteries for its power supply. "TPA" stands for "Transistor Phonograph Amplifier".
Another first for portable radios was the unique dial scale used in the 1000 and later series of Trans-Oceanics. The 1000 was designed with a cylinder dial scale that would rotate with the band switch allowing only that particular band scale to show.
