WHAT IS Podcasting
Podcasting, a is defined by Wicki as "a portmanteau of Apple's "iPod" and "broadcasting", and is a method of publishing files to the Internet, allowing users to subscribe to a feed and receive new files automatically by subscription." This method for distributing audio, video, and other media files over the Internet is not a new concept as it emerged in early 2000 in a variety of forms ranging from internet radio streams and downloadable programs usually developed by larger companies. Distribution remained an issue and was moved forward by improvements to MP3 players, such as Apple's iPod in 2001, and implemented by a program called (http://rss.userland.com/) Radio Userland. In 2003 regular podcasts started showing up on well known Web sites and software support spread through programs such as iTunes. As of late 2004 the usage of this term and its related technology is largely associated with audio content served by a variety of sources on a multitude of different topics.

Operating much like a magazine subscription, a podcast is delivered through a subscription "feed." Subscribers receive regular updates on the media files available for download from the sources they select usually at no cost.
