13. SONY TR-63 TRANSISTOR RADIO, 1957
Japanese entrepreneurs Masaru Ibuka and Akio Morita and were among the first to grasp the true potential of transistor technology, which had been invented at Bell Labs in the late 1940s. Step one: Secure a license from Bell Labs. Step two: Start cranking out cheap transistor radios. The TR-63 was their first big success, turning their company, Sony, into a global audio powerhouse. And why not? Prior to the TR-63, radios were big vacuum-tube-laden affairs. Now you could carry one in a jacket pocket and listen to it all day. Fun fact: The red dots on the dial show where American Civilian Defense broadcasts could be found, in case of a nuclear attack.
Lots of cool gadgets on the list, including many things you wouldn't be caught dead using these days. (no, not the Dustbuster, I mean things like the original Pong game or 300 baud acoustic modems; well, and the Dustbuster too)
