RSS: RSS stands for "rich site summary" or "real simple syndication". This refers to a method of syndicating information to a number of different software applications, including feed readers, which allow people to subscribe to a channel of content they are interested in. This content can include blog entries, news headlines, videos, even audio. An RSS document, which is called a feed, web feed, or channel, includes a number of details about the item, including the author's name, full or summarized text, and the publishing date.

RSS feeds are part of a system that helps users stay informed and connected while reducing the time and effort that is often part of surfing the web for interesting content. The technology behind this concept dates back to 1995, when members of Apple Computer's Advanced Technology Group developed the Meta Content Framework, which was designed to structure basic information called metadata about websites. However, the first version of RSS was created by Dan Libby and Ramanathan V. Guha, one of the creators of Meta Content Framework, while the two worked at Netscape. This first edition was released in 1999 and was quickly adapted by other technology companies and computer scientists.
