Engagdget published a guide to podcasting (time-shifted syndicated online audio/radio type content developed and popularized by Dave Winer and Adam Curry) by Phillip Torrone back in October of this year (pretty fast out of the gate):
This week’s How-To is a three part special complete with our first Engadget “Podcast” MP3. The first part is how to get “Podcasts” on your iPod. So what’s a Podcast? To put it simply, a Podcast is an audio file, a MP3, most likely, in talk show format, along with a way to subscribe to the show and have it automatically delivered to your iPod when you plug in to iTunes. The show isn’t live, so you can listen to it whenever you want.
Doc Searls may have said it best: “PODcasting will shift much of our time away from an old medium where we wait for what we might want to hear to a new medium where we choose what we want to hear, when we want to hear it, and how we want to give everybody else the option to listen to it as well.”
