Facebook's "Like" button is viewed across 7.5 million websites a total of 22 billion times per day. Which puts a lot of pressure on even the subtlest of redesigns.
This new redesign by Facebook is actually not so subtle though. The world's largest social network decided to completely drop its iconic "thumbs up" icon, replacing it with the mobile version of its Facebook logo (the F cut out of a white square with rounded edges). It also uses Facebook's darker, richer blue, instead of an old pale cloudy blue.
Here's the old button to jog your memory:
"We're already seeing a favorable increase in Likes and Shares with the new design and will be rolling these buttons out to everyone in the coming weeks," Facebook says.
"If you are currently using the old Like button, you'll be automatically upgraded to the new design as part of our roll out," the company added.
