Ron Williams Online News Publishing Network is a News Aggregator. Examples of this sort of website are the Drudge Report and the Huffington Post. There are also websites like Google News and DecaPost, where news aggregation is entirely automatic, using algorithms which carry out contextual analysis and group similar stories together.
News aggregation websites started with sites like the Drudge Report, NewsNow, Andrew Breitbart and the Huffington Post, where content was still entered by humans. Newer sites such as Google News and News Clusters on the other hand are based on algorithms filling the content from a range of either automatically selected or manually added sources.
