> Similarly for "Kleenex", "Q-tip", "Xerox", all of which are known by they generic names in Denmark and, AFAIK, the rest of Europe
Germany: Kleenex are Tempos (a different brand), Q-tips are Q-tips, Xerox are the generic Kopierer, no one would use that brand name here.
Where? I've never heard Q-tips in Germany except from Americans.

Most languages have eponyms, an English example would be "hoover" which is sometimes used instead of "vacuum cleaner", especially in USA.
Hoover
Biro
Transit van
Cashpoint is probably the winner - I've never heard anyone use anything else. I don't even remember whose trade mark it once was.

If one is interested in Romanian TV shows...
"Comrade Detective" was a pretty good show.
There's a dubbed version available on Amazon IIRC.
Though it is a golden egg for any company to get their brand name to be associated as the name of the thing. Which is pretty American.
It can backfire, though. When your brand name becomes a generic term for a type of product, it can invalidate your trademark. I did not even know Thermos was an actual company until I was ~20 years old.
