The original meaning of iconic was essentially “resembling an icon,” but today it often describes what is so admired that it could be the subject of an icon. And with that use, iconic has become part of the language of advertising and publicity: companies and magazines and TV hosts encourage us to think of some consumer item or pop star or show as first-rate or immortal or flawless—absolutely “iconic”—when that person or thing is actually simply widely known and—they assert—distinctively excellent.
