Apparently Google itself is a noun (as a company name), but has been turned into other forms by means of having it be a noun. (A verb meaning to Google something obviously) but even that didn't happen without reason.

Looks like that & a lot of terms in science & technology can be considered a
neologism.
Yay for the english language... the language that "has pursued other languages down alleyways to beat them unconscious and rifle their pockets for new vocabulary."*
