A brief history of our search interest in pumpkin spice lattes

6. …Which isn’t terribly surprising, given that it’s been on a steady increase every year — until 2018! Search interest dropped significantly in 2018, and only began rising again in 2021.

7. Speaking of PSLs, search interest in the pumpkin spice acronym grew annually alongside the full drink name. (Quick note that not all “PSL” searches are about the drink — PSL is also an acronym for other things, like Port St. Lucie, a city in Florida. But PSL spikes do seem to coincide with “pumpkin spice latte” spikes each fall, so clearly some of the interest overlaps.)
