What is a podcast?
Podcasts are like short radio shows. Publisher of a podcast, namely podcaster, periodically records the show and makes it available in MP3 or in any other media format so that his listeners, that is you, can download and listen to it whenever you want.
For example, you can listen to NPR or BBC radio news thru their designated podcasts. Note that podcasts are not only in audio, you can also find podcasts publishing video content.

Ziepod periodically checks subscribed podcasts for updates and notifies you when new content is available.
