RSS (Really Simple Syndication) allows for the syndication and distribution of content like news, blogs, and journals across multiple online channels simultaneously. It provides a standardized format for lists of content items with metadata like titles, dates, and descriptions. Users can subscribe to RSS feeds from various sources and tracking software will deliver new content to them as it is published. This allows users to choose what information they want to receive and stay updated in a more productive way than manually checking numerous websites. RSS feeds can be accessed through web page aggregators that display headlines or offline clients that deliver content via email.
