Time flies! Facebook turns 10

Happy Birthday Facebook!

The social network co-founded by Mark Zuckerberg in a Harvard dorm room turned 10 on Tuesday.

At the beginning, users could only join "the facebook" if they were at Harvard university, but that wasn't the case for long. Just one year after it was founded, Facebook dropped its "the" and had 6 million users.

Now, Facebook has 1.2 billion users.

The site is now worth $135 billion with revenues of $7.87 billion in 2013, including $1.5 billion in profit.

Globally, 556 million people now access the site every day on their smartphone or tablet and at the end of 2013, for the first time, Facebook made more than $1 billion in revenue from mobile advertising in just one quarter.

About six in 10 users log in everyday to share status updates, photos and of course, "like" things.

There are six billion "likes" per day.

Over the past decade, 400 billion photos were shared, and 7.8 trillion messages sent.

Facebook now employs 6.337 employees worldwide.
