What is a podcast?
A podcast is a regularly updated series of audio files from a content provider, the modern analogue of a radio program. The term was coined as a portmanteau of “iPod” and “broadcast”, though today podcasts are commonly downloaded or streamed onto any number of smartphones and other mobile devices.
How does a podcast work?
Most podcasts come in either audio or video format, and can be viewed or listened to using a variety of applications depending on how they are distributed. These applications are often called “podcatchers.” Podcatchers can automatically download new episodes of a podcast so the newest content is always available on the device of the listener or viewer.
