What is Podcasting?
Podcasting is delivering audio content to iPods and other portable media players on demand, so that it can be listened to at the user's convenience.
The main benefit of podcasting is that listeners can sync content to their media player and take it with them to listen whenever they want to. Because podcasts are typically saved in MP3 format, they can also be listened to on nearly any computer.
Podcasts are nothing more than RSS feeds with reference to a media file. RSS 2.0 supports enclosures, which are URL references to web content. This makes it possible to use RSS files to provide information about web content in a standard XML-based format. Podcasts are simply the application of RSS enclosures to audio files.
Popular implementations of Podcast are lecture recordings, Activity-based recordings, radio, etc.
