A transistor radio is a small portable radio receiver that uses transistor-based circuitry. Following their development in 1954, made possible by the invention of the transistor in 1947, they became the most popular electronic communication device in history, with billions manufactured during the 1960s and 1970s.
In their 1934 poll, 56 percent deemed the car radio a âdangerous distraction.â Arguing the other side was the Radio Manufacturers Association, who pointed out that car radios could be used to warn drivers of inclement weather and bad road conditions, as well as keeping them awake when they got drowsy.
