Shortly after posting my post about the Cisco Discovery Protocol, I remembered CDP stood for something else in the field of technological technology. That’s right, it was also the model number for the world’s first commercially available CD music player!

From the Polish Wikipedia, which is also the source of the image by Atreyu:

Odtwarzacz CD Sony CDP-101 był pierwszym urządzeniem tego typu na rynku konsumenckim. Jego premiera miała miejsce 1 października 1982 roku. Cena w dniu premiery na rynku japońskim wynosiła 168 000 jenów.

And people say they don’t learn anything from my site.

CDs seem so recent, relatively speaking, and yet there it was years before I was even born. Go figure.
