Podcasting is online audio content that is delivered via an RSS feed. Many people liken podcasting to radio on demand. However, in reality, podcasting gives far more options in terms of content and programming than radio does. In addition, with Podcasting, listeners can determine the time and the place, meaning they decide what programming they want to receive and when they want to listen to it.
Listeners can retain audio archives to listen to at their leisure. While blogs have turned many bloggers into journalists, podcasting has the potential to turn podcasters into radio personalities.
