I'll admit to being slow off the mark on Podcasting. Now I load a dozen 'cast onto my iPod and listen during my commute into the city. These include BusinessWeek's Cover Story review, Danny Sullivan's The Daily Searchcast, CBS's NFL Today Hot Topic and Paul Colligan/Alex Mandossian's MarketingOnlineLive*.
iTunes has nearly 20,000 poscasts available; most not of any real value except to the 'caster themselves. However, Apple makes it easy to get on the list and to subscribe and receive updates. Other directories exist include Podcast.net, iPodder and Podcast Alley.
Great entertainment; but is this a viable online marketing channel? Can a Podcast create sustainable monetization? The initial podcasts were nothing more than audio blogs. Even today, anyone with a microphone and a dream can be a 'caster. But will anyone listen in? Just like blogs, will anyone visit? Early bloggers were teenagers that used blogs to share their feelings and thoughts with their friends. Podcast has moved up the evolution scale (sorry creationist) very quickly and are now (or about to be) a big channel for business. Blogs may become big for business.
Read about the rush to Podcasting in the Wall Street Journal, "Is Anybody Out There?" by Sarah McBride and Nick Wingfield.
The same rules apply for Podcasters as with Blogs. If the message is self-serving, if the content is not updated frequently, if the speaker is boring, the audience will go away (or worse, bad mouth your attempt). I didn't find any corporate podcasts; but that is just a matter of time (let me know of any you find).
Can Podcasts be monetized? Google AdSense won't work (not yet atleast); so it's about sponsorship and voice-ads (think radio). It can also be subscriptions. At Audible you can subscribe to the daily Wall Street Journal, which provides verbal readings of key stories. And you don't need to learn how to fold a newspaper on the train (something I can never get right). You can also subscribe to educational podcasts, like The AffiliateGuy. For $47/month you gain access to exclusive content for Affiliate Marketers. Even Rush Limbaugh has his own fee-based Podcast.
The BusinessWeek Podcast contains a brief sponsor message, a 30 second spot. The balance of the 'cast is commercial free. And like Tivo (kinda) you can fast forward past the commercial on your iPod or other MP3 devices.
If you have interesting content to share and can establish a following; you can make money as a PodCaster. And if you are an advertiser looking to reach a hip new audience, maybe PodCasting is the way to go.
* I wrote Paul an email about his podcast, and imagine my surprise as I was riding the train hearing my name over his 'cast. This shows the power of PodCasting as a two-way communications between the PodCaster and the audience (think comments in Blogs).
