In early 2015, LINE launches “LINE TV”, a video streaming platform. Within a month, the APP of “LINE TV” has been downloaded for more than one million times. This study uses the concepts from the extended unified theory of acceptance and use of technology (UTAUT2) and digital lifestyle to investigate factors that may influence users’ behavioral intention and use behavior of LINE TV. This study conducts a web survey and collects 776 samples. Results show that performance expectancy, facilitating conditions, hedonic motivation and habit all positively predict users’ behavioral intention, which further positively predicts use behavior. Additionally, different digital lifestyles make significant differences on behavioral intention. The findings have implications for marketing.
