An RSS feed (also known as an XML or news feed) is a listing of a Web site's content. It is updated whenever new content is published to the site. News readers "subscribe" to the feeds, automatically downloading lists of stories at a user-specified interval, and presenting them in the news reader.
A news feed might contain a list of story headlines, a list of excerpts from the stories, or a list containing each story from the website. All news feeds have a link back to the Web site, so if a headline catches your eye, click on the link for that article. RSS feeds are syndicated content.
