xml logoWhat Is RSS? Really Simple Syndication (RSS) is a family of web formats used to publish frequently updated digital content. Most commonly used to update news articles and other content that changes quickly, RSS feeds may also include audio files (PodCasts) or even video files (VodCasts). Users of RSS content use programs called feed 'readers' or 'aggregators' (newer versions of Web browsers offer built in support for RSS feeds): the user 'subscribes' to a feed by entering the link of the RSS feed into their RSS feed reader; the RSS feed reader then checks the subscribed feeds to see if any have new content since the last time it checked, and if so, retrieves the new content and present it to the user.
