This study examines the implications of social networking web sites (SNSs) within romantic relationships. Specifically, Knapp’s (1978) stage model of relationships is examined through a new lens wherein the role of SNSs, specifically Facebook, is explored in the escalation stages of romantic relationships (i.e., initiating, experimenting, intensifying, integrating, and bonding). Furthermore, this study sought to discern the interpersonal and social implications of publicly declaring oneself as "In a Relationship" with another person on Facebook (i.e., going "Facebook official" or "FBO"). Ten mixed-sex focus groups were conducted. Analysis revealed that Facebook is one of the primary means of uncertainty reduction in the initial stages of relationship formation. College students consider FBO to be indicative of an increased level of commitment in relationships. Typically, relationship exclusivity precedes a discussion on becoming FBO, which occurs when the relationship is considered stable. Going FBO has implications for the public proclamation of one’s relationship status as described in Knapp’s model, and these results differ for men and women. Theoretical implications for the role of SNSs in romantic relationships are discussed.
