Is Facebook Becoming Obsolete? A Mathematical Analysis


In 2007, Facebook overtook MySpace to become the #1 online social network in the world. In 2009, MySpace effectively became obsolete, but Facebook has continued its dominance all the way to today. Still, with many other social networks sprouting up and with some recent negative news about Facebook, people wonder: when will Facebook’s stay at the top end, or will it?

We will attempt to answer this question by forming a mathematical model for how users enter, and leave, a social network, and fitting this model to how popular Facebook is in Google searches.
