Podcasts are considered to be media rich communication tools.

Podcasting is the process of recording audio or video files and distributing them online via RSS subscriptions, in the same way that blog posts are automatically fed to subscribers. Podcasting combines the media richness of voice or visual communication with the convenience of portability. Audiences can listen or watch podcasts on a blog or website, or they can download them to phones or portable music players to consume on the go. Particularly with audio podcasts, the hands-off, eyes-off aspect makes them great for listening to while driving or exercising.
