Facebook's new emoji symbols serve both users and advertisers.
The company chose the subjects for its emoji pieces after a year of research in focus groups and surveys. The new symbols mirror the five emotions people most commonly want to express.
The symbols are based on the classic smiley face and offer button responses of like, love, laughing, surprised, angry and sad.
To reach them, hold the "like" button on mobile, or hover over the like button on a desktop, and the five symbols come into view.
At least 1.6 billion people visited Facebook in the fourth quarter of last year, and 1.4 billion said they visit Facebook, every day.
The emoji don't need to be translated into other languages. Facebook designed them to be clear expressions used by customers around the world.
Called Reactions Emoji, the new symbols give the data-driven company even greater insight into what interests users. In turn, that could give Facebook's advertisers greater insights into what status updates would be best.
