If you've been on Facebook recently you've encountered other users using a new feature launched by the social networking site called Look Back, originally created to celebrate the tenth anniversary of the site, which instantly creates personalized video montages of a user's top posts. The company reported that by Wednesday last week hundreds of millions of movies have been made.

The videos are each a minute long and shows user's top photos, top status updates and some of their memorable moments, based on content they've already shared. The company recently launched a news feed app called Paper in a move to break up its different services into individual apps, something similar to what Google Apps has done for its services.

Facebook said: "This is a small gesture to thank the over one billion people who are on Facebook by providing a unique way to look back at some of their biggest moments." To access your own Look Back video, all you have to do is head to Facebook.com/lookback.

The feature is only available to users who have set their account to English, Spanish, Italian, German, Frech, Turkish, Indonesian and Brazilian Portuguese. Also, users who haven't been on the social network for a long enough time, or those who rarely post content, won't be able to see a personalized movie. Look Back videos will be available online for about a month. To keep the videos permanently, users have to share them on their Facebook Timeline.

In a creative use of the feature, fans of the Breaking Bad franchise YouTube users Derick Watts and the Sunday Blues created their own inspired Look Back video featuring highlights from fictional Walter White's timeline as if he had joined the Facebook Look Back film craze. White (Bryan Cranston) joined Facebook in 2006 and initially shared his family life and chemistry teacher work before his life went down a different route, familiar to viewers of the show.
