What is a PodCast?
A podcast is a web feed of audio or video files available for either direct download or on a subscription level. Programs like iTunes or Yahoo can collect subscriptions of these feeds. You may download your subscriptions to devices like iPods in order to carry the PodCast with you so you can listen or view the files on demand, on your schedule.
Why Should I Subscribe?
You'll get the latest file as soon as it is available, without having to constantly check for updates on your own. A reader like iTunes can download the files on a schedule to your iPod so you can listen to, or watch, your collection of PodCasts at any time.
