A podcast is a collection of digital media files which is distributed over the Internet, often using syndication feeds, for playback on portable media players and personal computers. The term podcast, like "broadcast", can refer either to the series of content itself or to the method by which it is syndicated; the latter is also termed podcasting. The term podcast should not be used to describe individual files. The host or author of a podcast is often called a podcaster.

The term is a portmanteau of the words "iPod" and "broadcast", the Apple iPod being the brand of portable media player for which the first podcasting scripts were developed. These scripts allowed podcasts to be automatically transferred to a mobile device after they are downloaded.

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.
