A news feed (newsfeed) is list of newly published content on a website. End users can receive push updates for new content on a site by subscribing to the site's news feed.
Feeds are designed to be machine-readable so they can they can transfer information from one computer to another without human intervention. Browser plug-ins, client-side applications called readers or application program interfaces (APIs) translate the code into human-readable text. Typically, each item in a news feed consists of a headline that links to the actual content and a brief summary. Many social networking sites, including Facebook, Twitter and LinkedIn have proprietary news feeds that provide site members with status updates, tweets and updates from LinkedIn colleagues.
News feeds are useful for aggregating Web content by topic, author or website. Instead of visiting multiple Web pages to check for new content, the user can look at the summaries and choose which links to follow for the full versions. There are two popular formats for creating news feeds: Atom and RSS. Items can be organic, which means they are user generated --or they can be sponsored, which means a client has paid to have the content included in the feed.
