The aim of this research is to explore how video length and appeal impact video addiction. This research conducted two experiments to investigate how two different video lengths affect young consumers’ video addiction, with attention as a mediator and video appeal as a moderator. Accordingly, the independent variables are short- and long-form videos; the dependent variable is video addiction. In Study 1, the results showed that video length affects video addiction through attention paid to said videos. In Study 2, video appeal showed moderating effects on the relationship between video length and attention paid.
