Facebook's "like" button is not going away, but it is about to get some company.
Facebook has been testing alternatives to "like" in about a half-dozen countries. On Wednesday, the social network will start making "haha," ''angry" and three other responses available in the US and the rest of the world.
In changing a core part of Facebook, the company says it tried to keep things familiar. The thumbs-up "like" button will look the same, without the other choices cluttering the screen or confusing people. Users will have to hold that button for a second or two for the alternatives.
The rollout is expected to take a few days.
Users will get the feature automatically on web browsers, but an app update will be required on iPhones and Android devices.
