What is a Podcast?

A podcast is a series of electronic media files, such as audio or video, that are distributed periodically over the Internet by means of a Web feed. Podcasts are distinguished from other methods of distributing media because users can choose to subscribe to them, using software capable of reading feed syndication formats such as RSS, and thus can receive new media files as they are made available. A podcast’s content can often also be accessed by direct download or streaming.
