Una delle prime definizioni del termine Social Media fu coniata da Andreas M. Kaplan e Michael Haenlein (2010) “Social Media is a group of Internet-based applications that build on the ideological and technological foundations of Web 2.0, and that allow the creation and exchange of User Generated Content.” Tale definizione è legata al concetto del Web 2.0, introdotto da Tim o’Really, quale piattaforma per servizi unita a una buona dose di “coinvolgimento sociale degli utenti come creatori di valore”.
