What an RSS feed is
RSS, which stands for Really Simple Syndication, is a web format that lets a website publish a constantly updated list of its latest content in a standard file. Instead of visiting many sites to check for new articles, you can subscribe to their feeds in a single app called a feed reader, which gathers everything into one place. RSS has quietly powered blogs, news sites, and podcasts for more than two decades.
How a feed works
A site's RSS feed is a file, usually written in a structured format called XML, that lists recent items with details such as each one's title, a summary or full text, a link, and a publication date. Whenever the site publishes something new, it updates the feed. The file lives at a web address, and readers periodically check that address for changes, so subscribers see new items soon after they appear.
Feed readers
To follow feeds you use a feed reader, an app or website that stores your subscriptions and shows new items as they arrive, much like an inbox for content. You add a feed by giving the reader its address, though many readers can find the feed automatically from a site's homepage. Everything you follow then appears in one chronological list, free of the clutter, ads, and algorithms of individual sites.
Podcasts run on RSS
Podcasting is built on RSS, even though most listeners never realize it. A podcast is essentially an RSS feed whose items each link to an audio file. When you subscribe in a podcast app, you are subscribing to that feed, and the app downloads new episodes as the feed updates. This open foundation is why a podcast can be played in almost any app rather than being locked to a single platform.
Why RSS still matters
RSS faded from the mainstream after Google shut down its popular Reader service in 2013, and social media feeds took over as the way most people discovered content. Yet RSS endures because it is open, free, and private: no company controls your feed, no algorithm reorders it, and nobody tracks what you read. For people who want to follow sources directly, on their own terms, it remains quietly unbeatable.
The bottom line
An RSS feed is a standard, updating file that lets you follow a website's latest content in a reader app instead of visiting the site. It powers blogs and every podcast, and its appeal is simple: an open, chronological, private way to keep up with the sources you choose. Though it is less visible than it once was, RSS remains one of the web's most useful quiet technologies.
