Tamagotchi
The egg-shaped virtual pet that defined a generation's backpack clip-ons — and, decades later, actually came back as a real sales trend, not just nostalgia.
Tamagotchi 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.
Why it's trending
Bandai's 1996 original sold 400,000 units in its debut year in Japan, then 13 million more in 1997 as the craze went global.
A 2019 relaunch aimed at pure nostalgia sales instead found a surprising number of buyers who'd never owned one — younger kids discovering it for the first time, not just millennials reliving childhood.
