A bit more trivia...

The huge success of the TR-63 helped Tokyo Tsushin Kogyo (aka "Totsuko") decide to change its company name to Sony Corporation in 1958. For the few years prior, "Sony" had simply been a brand name attached to the company's fledgling line of transistor radios. (Check out the retro Sony logo - I like it!)

At the time, the company's co-founders felt the Japanese name was too hard to pronounce and remember by foreigners. They decided the name change would help them expand and become well known worldwide. And as they say, the rest is history.
