Micropart Advertising

Radio, TV and online media are sold by time of day - what's called daypart advertising. It only stands to reason then that podcasts are sold in microparts. That's the idea behind PerSecondPodcast. The project, run by four Yale students, sells ads on podcasts in as little as one second increments! What's also interesting is that they are taking all of their ads, putting it on an iPod and burying it as a virtual time capsule.
