What is a news reader?
RSS/News Readers (also called Aggregators) download and display RSS feeds.   If you're using Mozilla's latest version of Thunderbird (email) or Firefox (web browser) or Apple's Safari, then you already have an RSS news reader.

Many free news readers can be downloaded and installed on your computer.
