A podcast is traditionally an audio series delivered over the Internet as a download, in a style similar to radio shows. However, the term has now has grown to include video shows, as well.
A Podcast is a video or audio recording that is available via the Internet. They differ from other audio or video content because they are downloaded rather than streamed and are often transferred to media player devices such as the iPod automatically.
Podcasts were traditionally published via syndicated web feeds such as RSS or Atom and automatically downloaded by the user's podcast aware "RSS Reader".
The name "Podcast" is a portmanteau of the word "pod" from iPod and "cast" from Broadcast or Webcast.
Podcasts generally follow a regular schedule, such as weekly or monthly programming, but others are produced on less frequent or regular schedules.
Podcasts also tend to follow a central subject matter and often include guests on the show to discuss aspects of that topic.
