"The ability to upload and store sermons is a real benefit for our people. Folks who miss don't have to miss out on the teachings and our folks out of town, including one man working in China, listen to it at their convenience. The process is simple and the Web Guys led us through the whole learning process. It is one of the most valuable and used parts of our site." -- Tim Stutler Glasgow Cumberland Presbyterian
A podcast is a digital media file, or a series of such files, that is distributed over the Internet using syndication feeds for playback on portable media players and personal computers. A podcast is a specific type of webcast which, like 'radio', can mean either the content itself or the method by which it is syndicated; the latter is also termed podcasting.
The host or author of a podcast is often called a podcaster. In other words, a podcast is a collection of files (usually audio and video) residing at a unique web feed address. People can "subscribe" to this feed by submitting the feed address to an aggregator (like iTunes - software that runs on the consumer's computer). When new "episodes" become available in the podcast they will be automatically downloaded to that users computer. Unlike radio or streaming content on the web, podcasts are not real-time. The material is pre-recorded and users can check out the material at their leisure, offline.
