RSS (Really Simple Syndication) is an XML-based format for sharing and distributing web content, such as news headlines. Using an RSS reader, you can view data feeds from various news sources, including headlines, summaries and links to full stories.
RSS readers will download and display RSS feeds for you. A number of free and commercial RSS readers are available for download. Some RSS readers come as plug-ins for popular web browsers, some are stand-alone programs. Some web portals allow you to add RSS feeds to your personalized web page
