It's just a little, clickable icon. But Facebook's "Like" button, with its omnipresent "thumbs up" symbol, has made the company
billions of dollars. The story of the button's creation can be traced to a core group of Facebook veterans.
Facebook Director of Engineering
Andrew Bosworth posted his version of the button's history on
Quora.com
in 2010. Bosworth writes that he and a small group of co-workers worked
on the project, codenamed “Props.” They debated other ideas including
plus/minus signs and star ratings. According to Bosworth’s post, the
Like button was originally going to be called the "Awesome" button.
Apparently, founder Mark Zuckerberg put the kibosh on that idea.
