What's Podcast?

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 host or author of a podcast is often called a podcaster.

These scripts allowed podcasts to be automatically transferred to a mobile device after they are downloaded. from Wikipedia
