What's a Podcast?
A podcast is a digital media file (such as MP3) that is distributed by subscription (usually free) over the Internet using syndication feeds. It can be played on mobile devices and personal computers.
Contrary to popular belief, you do NOT need an iPod or any other portable media player to play a podcast. Your personal computer probably already has the required hardware and software to play a podcast.
A podcast is distinguished from other digital media formats available on the Internet by its ability to be subscribed to and then downloaded automatically using software (such as Apple's iTunes) capable of reading syndication feeds.
