This article presents a reasoned review of the works produced on the "FoMO" phenomenon, starting from the date of the first scientific paper. FoMO stands for Fear of Missing Out. It is a specific form of social anxiety explained by the need to remain in contact with other people and the fear of being excluded from an event or social context. According to the definition of Andrew Przybylski, the first author to deal with FoMO, it is possible to define it as «a pervasive apprehension that others might be having rewarding experiences from which one is absent (..) is characterized by the desire to stay continually connected with what others are do-ing» (Przybylski et al., 2013, p. 1). In the US, many efforts were done on FoMO, while the same cannot be said for the rest of the world. Nevertheless, this is a con-dition that we can be observed everywhere. This review aims at defining the field for future insights on the subject.
