The purpose of this research is to investigate motivations and factors that influence people¡¦s willingness to use mobile digital TV. Potential motivations, including fashion, information, mobility, social and entertainment, and their effects on the perceived usefulness and attitude are investigated. The research used quantity analysis, Snowball Sampling and convinence sampling to collect 316 samples. The data were analyzed using LISREL, the structural equation modeling tool. The result shows that information and fashion are two major motivations that had positive influence to the perceived usefulness. Social motivation and entertainment motivation had positive influence on attitudes. Attitudes and the perceived usefulness had positive influence on the intention to adopt mobile TV.
