Communication technologies are widely used to manage interpersonal relationships, but little is known about which media are most useful at different stages of relationship development, and how the pattern of usage may be influenced by contextual factors or users’ gender. Drawing on theories of relationship development, this study examined usage patterns among 34 college students participating in six geographically stratified focus group interviews. Analyses revealed a sequence of media use tied to stages of relationship development – from Facebook in early stages to instant messaging and then cell phones as a relationship progressed. Judgments about the efficacy and appropriateness of using a medium were based on how well its salient features matched prominent goals or addressed major concerns of a relationship at the given stage. International students added two technologies to the sequence to accommodate time differentials and distance from communication partners. Males were less explicit about the sequence, except when referring to cross-sex relationships.
