Recent years, CGM (Consumer Generated Media) services, such as YouTube and nicovideo, are growing into social contents communication media. A lot of movies are posted to a CGM site, and many users are viewing them every day. Some web news articles mentioned that the diversity of movie contents might decrease in CGM site. The authors believe that contents diversity is necessary to keep CGM site activity, and for cultural sustainability. The authors try to measure diversity of movie contents of a CGM site quantitatively. They propose two quantitative metrics of contents diversity, and apply them to a CGM contents in nicovideo.jp.
