RSS, which stands for Really Simple Syndication, is a standard format used to automatically deliver real-time content updates to subscribers. It is primarily used for the distribution of news, blog updates, audios, videos and other frequently updated content.
Users who wish to receive updates from a particular website can subscribe to its RSS feed using an RSS reader. Whenever content is updated or new content is added to that website, the RSS reader picks it up and presents it to the subscriber without the subscriber having to visit the website directly.
The popularity of RSS has declined with the rise of social networking, but it is still a valuable tool for those who want to get content updates without having to rely on third-party platforms.
