1 Billion People Used Facebook on Monday

Facebook reached a major milestone this week. On Monday, more than 1 billion people used the social networking site. That's the first time in Facebook's history that 1 billion people logged on in a single day.

"On [Monday, August 24], 1 in 7 people on Earth used Facebook to connect with their friends and family," Mark Zuckerberg wrote, on Facebook of course.

Zuckerberg went on to say that he is "so proud" of the global Facebook community.

"Our community stands for giving every person a voice, for promoting understanding, and for including everyone in the opportunities of our modern world," he said. "A more open and connected world is a better world. It brings stronger relationships with those you love, a stronger economy with more opportunities, and a stronger society that reflects all of our values."

Founded in 2004, Facebook reached 1 billion users in October 2012. As of June 30, 2015, Facebook had 1.49 billion monthly active users.

Facebook has also released a special video to commemorate the milestone. Check it out below.
