Facebook has granted a Missouri fathers tearful request to unlock his dead sons social media page and give him access to a video compilation of photos and posts he had been unable to view. This week, to commemorate its 10th anniversary, Facebook has generated automated Look Back videos of users social media pages, showing highlights of their time on the site. Users must sign on to their Facebook page to instruct the social network to play their 62-second personalized video. John Berlin of St. Louis, Missouri, made a tearful, emotional plea in an online video to Facebook founder Mark Zuckerberg on Wednesday, asking to see such a video compilation of his late sons Facebook page.
