The launch upends its founders’ original mission of creating an app with ‘No Ads! No Games! No Gimmicks!’ This week, WhatsApp did something its founders said it would never do: it’s putting advertisements inside the app. It ends WhatsApp’s decade-plus run of offering an ad-free messaging and calling experience.

WhatsApp said ads will be targeted to users based on information like the user’s age, the country or city where they’re located, the language they’re using, the channels they’re following in the app, and how they’re interacting with the ads they see.
