Casual tech observations: The transistor was invented 1947. The first transistor radio was the Regency TR-1, 7yrs later. (https://en.wikipedia.org/wiki/Regency_TR-1)

The Sony TR-63 (https://www.siliconchip.com.au/Issue/2016/January/Sony%E2%80%99s+TR-63+shirt-pocket+transistor+radio) became the world's first widely-adopted pocket transistor radio in 1957.

One thing people often overlook is that the circuits of these pioneering radios were built on circuit boards, the one other thing that enabled all the technology we know today.
