Facebook recently turned 10 and to celebrate that milestone it showed off its data mining prowess by letting users automatically generate “Look Back” movies. To create these movies, the world’s largest social network takes many parameters into account and then comes up with a short movie that features a users’ most popular photos uploaded throughout their time on Facebook. Not all of its more than one billion users like the automatically generated movies, some believed that the pictures were not quite representative of what they are now as opposed to what they were a few years ago. At first it was just rumors that Facebook will launch an editor to end these complaints, but now its official. You can easily edit Facebook Look Back movie using the new editor.
