"RSS is an acronym for Really Simple Syndication and Rich Site Summary. RSS is an XML-based format for content distribution. Webmasters create an RSS file containing headlines and descriptions of specific information. While the majority of RSS feeds currently contain news headlines or breaking information the long term uses of RSS are broad.

RSS is a defined standard based on XML with the specific purpose of delivering updates to web-based content. Using this standard, webmasters provide headlines and fresh content in a succinct manner. Meanwhile, consumers use RSS readers and news aggregators to collect and monitor their favorite feeds in one centralized program or location. Content viewed in the RSS reader or news aggregator is known as an RSS feed."
