PodCast: what you want, when & where you want it.
A podcast is a downloadable file, typically MP3 audio, delivered via an RSS feed, which use a technology called XML. You can download the file to an iPod or other personal listening device and listen wherever you like, or you can download the audio directly to your hard drive and listen from your computer.

RSS Feeds and Podcasts
The profusion of Web sites and Weblogs makes it difficult to keep up with the latest postings on all your favorite sites.

Now, instead of going to each of your favorite sites to see what's new, you can assemble your own collection of favorites and have updates from those favorites automatically delivered to your computer or digital device. It's like having the newspaper delivered to your doorstep, only now you are the editor in chief who decides what news you want to keep up with. You decide what content you want, and it is delivered to you whenever there is something new. WNPR is proud to offer you content via this emerging technology.

RSS feeds: the Web comes to you
RSS (Really Simple Syndication) allows you to automatically get Web content from a variety of sources delivered to your computer.

To use this service, you must register with a free RSS news reader or aggregator. (Entering "RSS readers" or "RSS aggregators" into a search engine such as Google will produce a list of available services.) Once registered, you specify which sites you would like to receive updates from by adding specific RSS feeds to your customized list. You can then view regular updates from all the feeds together, or you can view each feed separately. RSS is handled through a technology called XML (eXtensible Markup Language). (Please note that the XML links on WNPR.org merely indicate that we provide this service; if you click on the XML link itself, you will see only the raw RSS feed in XML code.)
