The "Ch-ch-ch-Chia!" terra cotta planter that's outlasted almost every other novelty fad from its era — and is still a top holiday gift decades later.
Chia Pet 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.
Joseph Pedott discovered the Chia Pet concept being imported from Oaxaca, Mexico at a Chicago housewares show in 1977, licensed it, and built an ad campaign around the now-iconic jingle.
Unlike most 1970s novelty fads, it never really stopped selling — roughly 90% of sales still happen during the holiday season, and it's been preserved in the Smithsonian's National Museum of American History.
