A podcast is an episodic series that is typically presented like a radio show, though instead of being broadcast over the airwaves, a podcast is either streamed live over the Internet or available via download.

Successful podcasts are built around a central theme and the content serves to be either:

  • Informative
  • Entertaining
  • Or both

A podcast is available as a set of digital media files which a user can set up so that new episodes are automatically downloaded or streamed via web syndication to the user’s own local computer or portable media player.

The word arose as a hybrid of “iPod” and “broadcast.”

Podcasts are unique in that they are both content and they are a platform. The content can enhance a relationship between the brand and the listener, answer questions and support services and products, among other things. But podcasts can also be a source for additional revenue through the form of ads or sponsorship.
