Starbucks Pumpkin Spice Latte

Starbucks' Pumpkin Spice Latte is the most successful seasonal menu item in food history, generating over $1.8 billion in cumulative revenue since its 2003 creation. The PSL signals the unofficial start of fall for 45 million annual American buyers and has spawned a $800 million market of pumpkin-spice-flavored products, from cereal to deodorant. It even has its own Twitter account and is the subject of academic papers on seasonal marketing. Notably, the drink contained no real pumpkin until 2015. The PSL's cultural penetration is 30% deeper than the typical seasonal offering, making ordering one a meme-worthy signifier of autumnal identity.
