An RSS aggregator, also termed a feed aggregator, feed reader, news reader, RSS reader or simply aggregator, is client software or a web application which aggregates syndicated web content from online newspapers, blogs, podcasts, and video blogs (vlogs) in one location for easy viewing. RSS is a synchronized subscription system.
RSS uses extensible markup language (XML
) to structure pieces of information to be aggregated in a feed reader that displays the information in a user-friendly interface. The updates distributed may include small pieces of news items, videos, and podcasts.
