This happens a lot here in Brazil. Some brands are so famous that they are synonyms of some products, e. g. Gillette (razor blade), Bom Bril (steel wool), Insulfim (window film) and so on.

Xerox is a curious thing here. It is a so strong synonym to photocopy that almost no one remembers that it is a brand (at least, I don't remember seeing in person any Xerox device). It is so strong that xerox also means the shops were the photocopies are made.

Just place Google Maps over São Paulo, search for "xerox" and see what happens
