To celebrate its 10th birthday, Yelp has released a tool that will finally tell us exactly when craft beer surpassed PBR, ombre overtook Brazilian blowouts, and macarons began to take a bite out of cupcakes.
Yelp Trends is sort of like Google Ngrams for customer reviews instead of books. Enter up to three keywords, then choose your city and business category, and it will plot a graph showing the terms’ relative frequency in Yelp reviews over time.
Are macarons really the new cupcakes? Not quite, it seems:
