This thesis explores the distinctive forms of journalism that have emerged in mainstream news websites in mainland China. Two case studies, the 2008 Beijing Olympic Games and the H1N1 influenza pandemic in 2009, are employed to identify features in Chinese and Western news online. Specifically, a comparison is made between the in-depth news sections of popular mainstream news websites in China and those in the United States, the United Kingdom, and New Zealand. The study finds that the Chinese version of mainstream web news genre differs significantly from the Western version. This thesis argues that journalists’ practice is strongly context dependent. Distinctive economic, organizational, social and cultural factors contribute to shaping Chinese web journalism in a way that contradicts the notion of a homogeneous worldwide journalism or of a single set of norms for journalism. The study challenges the dominance of the political explanatory framework that considers political factors as the most important approach to study Chinese web-based media. In the face of a sparse literature and sporadic studies concerning the development of the internet as a novel platform in China for news production and transmission, this thesis aims to bring more academic interest to an overlooked research area and to contribute to a broader understanding of the actual diversity of global communication research.
