Podcasts are episodic digital narratives akin to radio series or audio documentaries. Although podcasts are generally audio-based, the media vehicle varies from video to PDF. Unlike radio programs, which air at certain times on certain stations, podcasts are generally streamed or downloaded from the internet.
Etymology: pod from iPod and cast from broadcast
