"Superstars" refers to highly famous and successful individuals in sports, entertainment, or business, characterized by exceptional talent, widespread appeal, and significant market demand, but also encompasses specific entities like the classic "Superstars" athletic TV show, the Adidas shoe, or even the "Super Star" invincibility item in Mario games, making the meaning context-dependent. The term highlights elite performance, driven by a mix of skill, effort, media, and luck, creating "winner-take-all" markets.
