A unique marketing predicament where a particular brand of a
product becomes so common or dominant, its brand name becomes the generic term for the entire
product category. Examples include Kleenex,
Vaseline, Xerox, Windex and WD-40. Some trademarks have actually lost their legal protection in the U.S, including Aspirin, Thermos and zipper.
#1: "Hand me a Kleenex, would you please? I'm all stuffed up."
#2: "These are Puffs. Shouldn't you say 'facial
tissue'?"
#1: "I just say Kleenex for all of them. The brand has committed genericide. Now just give me the damn Kleenex
already, my
nose is dripping!"
