As Internet technologies have developed, the popularity of Internet Protocol television (IPTV) has increased and the viewing behavior of the public has changed. In contrast to previous studies, we focused on the audience response to 3 new types of IPTV to analyze their competitiveness in the Taiwanese television market. Using the niche theory as a theoretical framework, we investigated the competition among 3 types of IPTV: PPStream, Tudou, and YouTube. An online survey was used to collect data for this study and 1,702 valid questionnaires were obtained. The data analysis shows that YouTube occupies the top position in terms of niche breadth, niche overlap, and competitive superiority. However, strong competition exists between PPStream and Tudou.
