What is an audio podcast?
An audio podcast is an episodic program delivered
via the Internet using an XML protocol called RSS. The publisher podcasts
the program by posting the episodes and the XML document to a Web server.
The consumer subscribes to the podcast using a client application, such
as iTunes, which regularly reads the XML file and downloads new episodes.
Podcasts are attractive to subscribers:
- Podcasts are free.
- New podcast episodes appear automatically and can be enjoyed anywhere,

How do podcasts work?
Podcasts consist of the episode files that you download and an XML file
that lists all the episodes. When you subscribe to a podcast, iTunes reads
the XML file and downloads the latest episode. Each day, iTunes rereads
the XML file. If a new episode is available, iTunes downloads it automatically.
How does iTunes support podcasts?
The iTunes client application that you download
and run on your Mac or PC allows you to subscribe to podcasts and listen to
or watch the episodes on your computer, iPod, or Apple TV.
The iTunes Store, which includes a podcast directory, helps you find
and subscribe to programs and helps podcasters publicize their programs.
Do I need an iPod?
No. Although you can download podcasts to your iPod
to play them on the go, you can listen to or watch podcasts on your computer
using iTunes or on your TV with Apple TV.
How do I unsubscribe?
If you are no longer interested in a podcast to
which you are subscribed, highlight the podcast in your Library and click
the Unsubscribe button in the lower lefthand corner of the screen. To
unsubscribe and delete all files related to the podcast, simply press
the Delete key after selecting a podcast.
