A podcast is a radio or video show that can be downloaded from the internet. The most popular way to experience a podcast is with the iTunes player from Apple (more).
Since a podcast is really just a media file and an RSS that is read by iTunes, you can listen to your favorite podcasts from other media players. Most companies producing podcasts have their own web site. This page lists podcasts being produced in Utah. If your Utah company has a podcast to advertise, please feel free to add it.
