Straight from BloggerCon III [4]'s open node...wikipedia's definition goes like this..."Podcasting is different than broadcasting and webcasting in that it "casts" audio not by a mechanism of centrally pushing audio out to listeners, but by the mechanism of the (distributed) listeners pulling (downloading) the audio files automatically. Podcasters publish (or "podcast") audio files, even in the likeness of radio shows, but it is the individual listener who initiates the "cast" through their subscription and automatic download of the audio program.

iPodder is a media aggregator which automatically downloads podcasts to your computer or portable device based on a RSS feed, leaving you 'one-click-away' from latest media feeds.
"Podcasting [7] is similar to time-shifted video software and devices like TiVo, which let you watch what you want when you want by recording and storing video, except that podcasting is used for audio and is currently free of charge. Note, however, that this technology can be used to pull any kind of file, including software updates, pictures, and videos.
"Blogs, often being self-published websites, provided a convenient means for individuals to self-publish audio files online. RSS already gave websites and blogs a means to summarize or list new content added to the site. Individuals already used RSS to poll websites for new content. Thus, the addition of audio file listings to RSS, and the addition of audio file downloading to RSS feed readers built upon the feed reader's existing methods for polling and downloading files, and upon the existing "reader driven" interaction with content publishers." - wikipedia
