Creating a small, cheep and durable replacement for valves (vacuum tubes).
N\A, but probably akin to then Western practices.

This transistor would lead to cheaper and smaller radios and TVs like the famous American Zenith Royal 500 of the 1950s. It was one of America's first moves in to the modern elctrial bussiness and it was seen as a national icon at the time.
It was meant to be replaced by ICs like the Philips TAA320 integrated circuit, so the circuit would have 1, not 3 cans on it!
Like all ICs, it is made to a JEDEC standard and ID numbering code after 1953. JEDEC was founded in 1958 as a joint activity between EIA and the National Electrical Manufacturers Association (NEMA) to develop standards for semiconductor devices. NEMA discontinued its involvement in 1979.
