What is RSS?
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, such as CNN.com, including headlines, summaries, links to full stories.

RSS Readers
RSS/News Aggregators (also called Readers) will download and display RSS feeds for you. Often, portable devices such as mobile phones and PDAs will come pre-installed with RSS readers. There are also a number of free and commercial News Aggregators are available for download. The website NewsonFeeds.com has a good list of RSS readers for your use.
