An RSS feed is a format for delivering regularly updated web content, such as blog entries, news headlines, or podcasts.  Subscribers can access RSS feeds through special readers or aggregators, which collect and present all the latest content from subscribed feeds in one location.  This makes it easy for people to keep up with their favorite websites in one place, without having to check each one individually for new updates. The podcast creator also submits their podcast's RSS feed to a directory.
