By including a URL to an audio file, podcasts use RSS enclosures to turn a news feed into a XML feed of audio files.
Podcasting in Action
Some potential uses for RSS with audio enclosures:
* Daily radio shows;
* Audio-based web logs;
* Company news for sales reps/road warriors;
* TIVO-like time shifting of broadcasts;
* Audio book promotions, i.e., a free chapter to get you interested;
* Music aggregators
Podcasting is immature technology, but offers the potential of becoming a significant new platform for web content distribution.
