Podcasting describes the process of using audio files to deliver syndicated website content to a digital audience.
Basically, in podcasting, you create audio files that are available on your website, which people can then download to their iPods or MP3 players and listen to. Podcasts are delivered through RSS (Rich Site Summary) feeds; users subscribe to various podcasts which are then checked regularly for updates just like blogs.
So podcasting is essentially another medium for delivering syndicated web content to your users. Abouts Linda Roeder calls podcasting blogging with sound.
And like blogs, services are being developed to help podcast fans find and sort through the ever-growing number of available podcasts. iTunes now has a podcast feature; sites such as Odeo.com allow users to find and subscribe to podcasts and even create podcasts of their own.
From the business point of view, the podcasting market may be well worth penetrating; with the widespread adoption of iPods and MP3 players, the potential podcasting market is growing all the time. Jupiter Research estimates that 18.2 million units will be shipped this year, reaching an installed base of 56.1 million units by 2010.
