A soft-sculpture doll craze so intense it caused real in-store riots — the purest pre-internet FOMO case study on this list.
Cabbage Patch Kids (1983) was a genuine nationwide craze decades before "going viral" was a phrase — and it's still made and sold today. This is a genuine pre-internet product — a real, nationwide sales phenomenon decades before social media existed, spread by nothing but word of mouth, in-store demonstration, and traditional advertising. Many of these are still in production today, largely unchanged.
Each doll shipped with its own name and "adoption papers," a gimmick that made the toy feel individually unique rather than mass-produced — a clever scarcity mechanic well before that language existed for marketing.
Holiday 1983 shortages led to genuine shoving matches and stampedes in toy stores across the US, widely covered by news outlets at the time. The dolls remain in production today.
