This chapter focuses on the importance of social media for pop culture fans. A web survey for fans of the Twilight Saga is implemented, using the concepts of cognitive, affective, and evaluative social identity and personal, product, and situational involvement. The purpose is to examine to what degree social identity and involvement can explain pop culture fans' future intention to travel, make recommendations to others, and use social media. Findings show that pop culture fans use social media to a large extent and that these means are important for making decisions about traveling and event participation. Moreover, the chapter shows that involvement dimensions are more important than social identity dimensions to explain future intention to travel, to recommend to others, and to use social media.
