A Podcast RSS feed is what permits the whole system to function. To start at the beginning, a podcast is a regular distribution of audio or visual files, called episodes, to a users podcast client. The people that utilise a podcast are called customers, and the podcast client is what allows them to subscribe to a feed. The podcast client is a programme that connects to the Net, searching for a categorical file the user has subscribed to, or told it to search for. That file is an RSS feed, a machine readable piece of coding that sends info back to the podcast client. RSS feeds may be employed to distribute many varieties of info, and were originally used for blogging and distributing blog posts to subscribers. As time went onnonetheless, a few folk had the idea of enclosing info regarding media files within the RSS feed so that software may be written to find that info and download the files described.
The Podcast RSS feeds became a hit, and podcast clients were quickly written to allow folk to use the new encoding. Podcasting became a technique of swiftly and cheaply sharing episodes with customers. Rather than requiring customers to visit the site that hosted the files everytime they needed to know if a new episode was released, users could depend on the podcast client to do the work for them, keeping track of numerous podcast rss feeds that interested them and downloading the files to be viewed when they wished.
Podcast RSS feeds are now used to distribute a number of different sorts of podcasts. Some producers use it as way to share a comedy or news program that they produce, others podcast to share music files they create, and some podcast to share video files they have created and to demonstrate their work. Podcasting permits the producers to become radio or television stars without the big investment in time and money that would be required to do that. Because podcasting has a low entry cost, requiring little more than a server and a domain to host the site and a method to record the media, crowds of people who otherwise would not have a chance to work in a media environment have a chance to do so thru their podcast rss feeds.
In this manner, podcast RSS feeds allow media publishing over the Net at a tiny part of the cost of different kinds of media distribution, permitting folk with way smaller budgets to challenge in some form. But podcast rss feeds are also tempting better established companies and groups as well, bringing folk from NPR radio stations and reports organizations like CNN who use podcasting as yet another means to distribute their product to end users.
