Facebook on Wednesday announced a move that has been long in the making: the company is extending the functionality of its ubiquitous Like button with six different reactions that help describe users' mood and express how something they see in the News Feed makes them feel.
Available to all users globally across all mobile and desktop platforms, the six new reactions—Like, Love, Haha, Wow, Sad or Angry—can be applied by holding down the Like button on mobile or hovering over the Like button on desktop.
