RSS is an acronym for Really Simple Syndication and Rich Site Summary. RSS is an XML-based format for content distribution with a specific purpose of delivering updates to web-based content.
Using this standard, webmasters provide headlines and fresh content, including Product Sales, Specials & New Product Announcements, New Auction Items, Price Changes, Job Openings, and so on.
Meanwhile, consumers use RSS Readers and News Aggregators to collect and monitor their favorite feeds in ONE CENTRALIZED PROGRAM OR LOCATION, usually in their Web Browser.
Content viewed in the RSS reader or news aggregator is known as a RSS Feed.
RSS is what an e-mail was once meant to be. And more.
