If you want to get to the top headlines from the Washington Post, the New York Times or CNET’s tech coverage you might turn to podcasts: free online video and audio entertainment.

The problem is that most people don’t even know what a podcast is. It has something to do with the iPod right?. In fact, it is not just for iPod users. It’s just the internet’s most versatile form of free radio or tv that can be delivered in whatever way you the user chooses. That’s the power of podcasts, they are made to be delivered to the user in whatever way he or she finds most convenient. They can even be listened to right from your browser! Did I mention that podcasts are absolutely free free free? (echo echo echo)

What is a podcast?

Wikipedia defines a podcast as “a series of digital-media files, which are distributed over the Internet using syndication feeds for playback on portable media players and computers. The term podcast, like broadcast, can refer either to the series of content itself or to the method by which it is syndicated; the latter is also called podcasting. The host or author of a podcast is often called a podcaster.”

Just like you subscribe to the newspaper, or set a TIVO to download your favorite shows, you can get podcasts delivered to you or in the case of some services set them up for streaming. They’re just common video or audio formats like avi or mp3 but they are wrapped in a “feed”. This is like a webpage that delivers text information, but instead it contains broadcast information to get it to the program you listen from. That’s the link that often ends with .RSS (but not necessarily) or is commonly associated with this symbol: . Read more about this symbol, check out http://www.feedicons.com.

What kind of content can be found in podcasts?

Podcasts can be professional quality audio and video from brands you know such as NPR, BBC, the Guardian. The power of podcasts, however, is the targeted and niche content. Interested in comic books, science fiction, science? There are podcasts that target your specific interests made by people like you. It’s not the same mainstream content as you might find in television or radio. So you can form your own channel of content that just feeds you the things you love and know about.

So how do I listen or watch?

PodcatcherMatrix provides an interface to help you compare various ways of receiving podcasts.

PodNova is a website made just for situations like this. The web-based PodNova player lets you subscribe to podcasts and has a very nice online application for doing this. It has an iTunes feel, but much simpler and no installations necessary.

Google Reader is one way to do it. Just plug the podcast url into the add subscription box and the reader should discover the RSS feed for you. The advantage of Reader, in my opinion, is the way it displays the notes from the podcast and the player all on one convenient window. It makes it really easy to follow along with shows that have web links. The Google custom homepage also accepts podcast feeds.

My Yahoo can also support podcast feeds and play them in your browser. Other online “podcatchers” include Newsgator, Netvibes, Pageflakes, Odeo

Juice is an open source free download to help organize your listening if you’d prefer a dedicated program for podcasts instead of your browser. Doppler is another such program. Even if you don’t have an iPod, you can still use Apple iTunes for free.

Looking for podcasts to listen to? Just do a Google search for any topic you might want to know about plus the word podcast and chances are you can get the content you’re looking for.
