This study aims to analyze the mindsets related to drama selection among audiences (viewers), targeting the rapidly growing drama industry. Under the logic that familiar cues facilitating quick decision-making, emotional contagion, and conformity pressure play important roles in drama selection, the authors analyzed the effects of variables such as online drama communities (online communities) and stars (lead actors, writers, and directors) on viewership ratings. Empirical analysis of 222 dramas broadcast on Korean terrestrial broadcasting networks from 2001 to 2009 revealed that internet communities serve as an important factor influencing drama viewership ratings. Specifically, the size of internet communities was found to have a significant positive relationship with drama viewership ratings. Furthermore, when analyzing the interaction effects between the size of internet communities and the name recognition of lead actors, directors, and writers, the interaction terms between lead actor name recognition and internet communities, as well as between director name recognition and internet communities, were found to have significant positive relationships with drama viewership ratings. However, the interaction term between writer name recognition and internet communities was found to have no significant effect on drama viewership ratings. These findings suggest that cues with high familiarity that can help viewers make quick decisions, as well as peer group pressure, play significant roles in enhancing drama viewership ratings.
