Hosting and RSS Feeds
Up till this point, starting your own podcast will cost nothing and it can continue to be so. There are free hosting services available, such as Podbean which offer 50MB of storage space, good enough for 54 minutes of audio in 128kbps MP3 format.
Once your media has been uploaded, you can use blogging services such as WordPress to publish your material. WordPress specifically has a podcasting category for posts and will also include the posts as part of your RSS feed.
However if you want to attempt podcasting for the long term, we recommend a professional hosting service and RSS provider. One of the best around is Libsyn, which will host your content, create an RSS feed for it and push it on to podcast aggregators such as iTunes. The service even has the capability to get your podcast out on the smartphone market via an app as well.
Libsyn is one of the premier podcast hosting services available for customers willing to pay.
