An icon, for our purposes, is something you can describe to someone who has never encountered it and still get a flicker of recognition. The silhouette does the work. A pair of white earbud cables against a solid colour. A yellow hazard suit in the New Mexico desert. Six seconds of someone falling over on a loop. You do not need the plot, the lyrics or the release date; you need the shape.
That test rules out a great deal of very successful culture. Enormous hits go past without leaving an outline behind, and the honest reason is usually that they looked exactly like the thing before them. It also lets in some things that nobody set out to make iconic at all: a stock photograph of a man turning his head, a shoe designed for boating, a Shiba Inu photographed on a sofa.
The second test is borrowability. Icons get taken and reused by people with no stake in the original — in costumes, thumbnails, memes, adverts, cover versions and student essays. The century has been exceptionally good at this, partly because the tools for reuse have sat in everybody's pocket since roughly the moment the smartphone became ordinary. A thing that nobody can remix stays merely popular.
The third is survival past its own moment, which is the one that disqualifies most candidates and cannot be judged for a decade or so. We try to be honest about that on each page. Where something is still too recent to call, we say so rather than pretending the verdict is in.
What you will not find: scores out of ten, a definitive ranking, or the claim that any of this is settled. Culture does not resolve into a league table, and the sites that insist otherwise are usually counting clicks rather than icons. Each page names the works, sets out the criteria it is using, and leaves the argument open — which is, after all, the point of having one.
