Despite social TV is still a new research concept, modest advances have been made though mostly in Western contexts with little attention being given to motivating factors of multiscreen social TV system use intentions. This article aims to close this literature void though not by focusing on the development of non-Western literature mainly but by focusing on augmenting the body of existing literature in multiscreen social TV system use intentions. To achieve this objective, past and existing literature both in Western and non-Western contexts was critically reviewed. A three-dimension (independent variable, mediating variable, and dependent variable) conceptual model was designed, based on the reviewed literature, with six constructs as independent variables namely: usability, sociability, social presence, multi-modality, user-generated content, and hedonism) theorised to be mediated by 'attitude' and behavioural intention is theorised as the dependent variable. The article concludes that the motivating factors of multiscreening social TV system use intention have not been exhaustively identified yet and multisreening is a complex social phenomenon that requires holistic research to understand deeper. Therefore, further empirical research is needed to provide further evidence-based understanding of the factors that motivate people to intend to go multiscreening while watching TV.
