Podcasts

A podcast is a series of digital-media files distributed over the Internet using syndication feeds for playback on portable media players and computers. The host or author of a podcast is often called a podcaster.

Though podcasters' web sites may also offer direct download or streaming of their content, a podcast is distinguished from other digital media formats by its ability to be syndicated, subscribed to, and downloaded automatically when new content is added, using an aggregator or feed reader capable of reading feed formats such as RSS or Atom.
