Abstract
This article presents an analysis of the flow of information in a network of online news sites. Social network theory and research on hyperlinked networks of Web pages are used to develop a model of information flow among Web sites. Kleinberg's authority-hub model is extended by introducing sources of information in the network. Significant support was found for a Source–Authority–Hub model, which shows the source, directionality, routing, and destination of news information flow through a network of authorities and hubs. This model demonstrates the ability of key Web sites to control the flow of news and information. Applications of the model to over-time data have the potential to predict future changes in the online news industry.
