The first Japanese transistor radio exported to the United States. Of greater historical importance than any other Sony transistor radio, the TR-63 was the beginning of the end of America's dominance in the consumer electronics industry. And this trend was accelerated dramatically with Sony's introduction of the TR-610 the following year, the first truly mass-marketed Japanese pocket transistor radio exported to the US.
