Two Classic Metaphors for New York City

1. The Big Apple – Originated 1920s jazz slang ("the big apple" = the big time, premier venue). Popularized 1970s tourism campaign. Evokes ambition, opportunity, center stage.
2. The City That Never Sleeps – 24/7 energy: subways, diners, theaters, markets, nightlife always running. Captures relentless pace and possibility.

Both endure because they reflect lived reality: NYC as ultimate destination and nonstop engine.
