The purpose of this study is to identify the factors affecting intention to use blog. For this end, the individual characteristics(Subject Norm, Perceived Enjoyment, and Self-Efficacy) and the variables used in TAM(Perceived Ease of Use, and Perceived Usefulness) were used to explain the research model. The suggested research model has been empirically tested with the questionaries. The result of research shows that the individual characteristics such as 'Perceived Enjoyment' and 'Self-Efficacy' and the variables of TAM have significant impact on users' intention using blog.
