What are RSS feeds?

RSS is known as either (1) Rich Site Summary or (2) Really Simple Syndication.  It is a web feed allowing users to access updates to online content in a standardized, computer readable format.

These feeds permit a user to keep track of information from multiple websites in a aggregator.  The aggregator will auto check the feed for new content, displaying the news content to the end-user.

This passing of information is referred to as web-syndication.  It is frequently used to provide updated information from many places into one easy to access location such as RSSNews.Press.  RSS feeds are used to update blog entries, news headlines, audio, and even video.

The idea of restructuring information dates back to 1995 after multiple failed attempts at web syndication.  RDF, the first version of RSS was developed by Dan Libby and Ramanathan V. Guha at Netscape.
