This paper analyzes the pricing strategy of Internet contents using the model. Two cases are considered : (i) the Internet content is monopolistic. (ii) the Internet contents are duopolistic. In the first, when the Internet content is monopolistic, the pricing strategy depends on the condition of the online advertising market. If the online advertising market is good, the monopolistic Internet content will be provided for free. Otherwise, the monopolistic Internet content will not be provided for free. In the second, when the online content is duopolistic, the pricing strategy depends on the condition of the online advertising market, the substitutability between two Internet contents, and quality of the content. If the relationship between incumbent Internet content and entrant Internet content is complementary, incumbent Internet content’s profit will be increased. If the relationship between incumbent Internet content and entrant Internet content is substitutable, incumbent Internet contents’ profit will be reduced .
