TIMELINE: Key Events in the Evolution of Facebook

Facebook rose from an idea cooked up in Mark Zuckerberg’s dorm room at Harvard University to one of the biggest tech companies in the world. Along the way it has changed dramatically, from a site used to rate university friends to a platform from which users can share photos, play games and interact across the web. Here, we pick out some of the key events in Facebook’s history.
