Abstract
Since its launch in February 2004, Facebook has become one of the most popular websites in the world, as well as a widely discussed media phenomenon. Unsurprisingly, the Facebook revolution has inspired a wealth of psychological study, which is growing exponentially. In this article, we review the recent empirical research into some of the key psychological themes concerning Facebook use. The review is organized according to common questions about Facebook culture and use being posed by academics and social commentators alike. These questions are grouped under three major themes, namely: (a) antecedents of Facebook use; (b) how individuals and corporations use Facebook; and (c) psychological outcomes or effects of Facebook use. To this end, we review over 100 recent publications (mostly empirical, peer-reviewed journal articles). We conclude by providing some suggestions for future psychological research in this rapidly expanding area of popular media culture.
