This paper proposes a new model for media credibility formation on the Internet through an analysis of quantitative research data. There are two main findings. First, there are various models depending on the patterns of Internet use. In the case of Internet users who only access websites operated by organizations, the longer they use the Internet per week, the higher their media credibility becomes. On the other hand, Internet users who access websites operated by individuals, there is no correlation between the length of media usage time and the media credibility. Second, "general media trust", a psychological aptitude that accounts for the level of credibility an individual has for any information source irrespective of media forms, has a great influence on credibility formation.
