Really Simple Syndication (RSS) formats are relatively new terminology in the World Wide Web. It gained wide popularity around 2006 during the blogging boom. If you visit blogs, you will be familiar with the orange RSS feed icon that they usually ask you to subscribe to. If you have an RSS feed on your website, your website visitors can benefit by subscribing to it. They will get information about new updates to your website right inside their favourite RSS reader including their browsers.
