a satoshi is the smallest monetary unit in the Bitcoin cryptocurrency, and is named after Satoshi Nakamoto, theprobably pseudonymousdeveloper(s) of Bitcoin.
I'm not sure if there would be any impact on bitcoin's popularity but it's good that the word has been acknowledged although I think it's a bit late.
The popularity and awareness about this issue is constantly increasing. Satoshi's validity for a language like English is a great improvement. The world is now learning Bitcoin and Satoshi, and it is officially registered.
