A 20-year-old Cambridge University history student has started Podcasting a 40-minute audio programme.

Podcasts are expected to become as diverse and niche-oriented as online blogs. People can subscribe to downloads that provide audio news from the stock market or updates on developments in a particular industry, as well as radio-style music shows. Podcasts can be stored in iTunes and played on iPods or any MP3 players at the listeners convenience.

Michael Rundle's inaugural podcast drew more than 300 downloads, and song submissions poured in.

Now students at the universities of York and Liverpool have joined the trend, and there is even talk of a music podcasting network linking college campuses throughout the UK.

Rundle told USA Today: "What we're trying to accomplish is a music democracy. There are no boundaries and no restrictions, and we are only limited by our own ingenuity and pool of talent."
