Podcast definition

Definitions of Podcasts on the Web:
Podcasting, a portmanteau of Apple's "iPod" and "broadcasting", is a method of publishing files to the Internet, allowing users to subscribe to a feed and receive new files automatically by subscription, usually at no cost. It first became popular in late 2004, used largely for audio files. en.wikipedia.org/wiki/Podcasts
