A pop icon is a celebrity whose fame in pop culture constitutes a defining characteristic of a given society or era. Although there is no single definitive test for establishing "pop icon" status, such status is usually associated with elements such as longevity, ubiquity, and distinction. Moreover, "pop icon" status is distinguishable from other kinds of notoriety outside of popular culture, such as with historic figures. Note, however, that some historic figures are recognized as having reached "pop icon" status during their era, and such status may continue into the present. (See e.g., Benjamin Franklin: , Mozart: )
