What is Podcasting?

Podcasts are digital media files (most often audio, but they can be video as well), which are produced in a series. You can subscribe to a series of files, or podcast, by using a piece of software called a podcatcher. Once you subscribe, your podcatcher periodically checks to see if any new files have been published, and if so, automatically downloads them onto your computer or portable music player for you to listen to or watch, whenever you wish.

Podcasting is an easy and powerful way to communicate your ideas and messages. You can potentially reach anyone with a broadband connection who is searching for podcasts and subscribes to your show. People who start podcasts usually want to deliver their content in a series, stretched out over a period of time. There are minimal equipment and start up costs if you already own a computer, and so this allows anyone who ever dreamed of owning a radio station (and some who didn't) the chance to transmit their ideas far beyond the reach of a radio transmitter.

Podcasters often start shows with the intention of building online communities, and often solicit comments and feedback on their programs. People use web blogs, groups, and forums to communicate with other listeners and the show's producers. Businesses are beginning to realize that podcasting is a cheap way to advertise to groups with very specific interests. Many large companies are starting to produce podcasts, both to communicate with their customers, and also with their own employees.
