Facebook's birthday present: A look back at your social life

Have you opened your birthday gift from Facebook?

This gift isn't for your birthday, though. Facebook marked its 10th year as a company on Tuesday. To celebrate, the social network offered its 1.2 billion users around the world what they're calling Look Back movies, made up of photos they've shared, along with their most popular posts.

Users can see, and share, their movie, which starts with the first photos they shared in the year they joined Facebook. To get your movie, go to facebook.com/lookback/.
