As an important component of web2.0 and a manifestation of new technology, podcasts represent the substantial change that occurs in the traditional role of audience and the corresponding communication mode. As both communicator and audience, a podcaster becomes the producer/provider of information, as well as the recipient of information. To explore the underlying reasons for the high-speed development of podcasting websites, and to thoroughly understand podcasters, this paper analyzes the activity of podcasters in Tudou.com, a popular Chinese podcasting website (www.tudou.com) using ethnographic methodology under the theoretical framework of Spectacle/Performance Paradigm. Specific conclusions on the characteristics, activities, developing trends and the impact of podcasts are drawn.
