Um. Since when?

Not exactly, that is a thing but it would be kind of the opposite of this. Let’s say a company was the first to ever make tortilla chips, and tortilla was the brand name. Then other companies started making something like tortilla chips with a different name, but then the name tortilla became so common that the first company lost its trademark so then everybody could call them tortilla chips.

I shouldn’t want that and yet I do.
