What is a Podcast?

A podcast is a digital audio file published online that can be downloaded to a computer or cell phone. Usually podcasts include multiple episodes, that are often focused on a particular topic or theme and are made available automatically to subscribers. 

Through podcasting, anyone can be their own radio host and share their own audio content. There are podcasts from: individuals, companies, media networks, celebrities, comedians, storytellers, etc. There are video podcasts too, although this is less common.
