Quick Answer: A podcast is a program made available in digital format for download over the Internet. Podcasts are primarily an audio medium, which is reflected in the term itself, a portmanteau of "iPod" and "broadcast" coined in 2004. The term used to refer to an episodic series of digital audio files that users can download to a personal device or stream to listen to at a time of their choosing. In the mid-2020s, however, video podcasts, either as primary content included in the feed, or as an external supplement to audio, have been popularized. In 2025, Bloomberg reported that a billion people were watching podcasts on video platform YouTube every month. This can cause issues where the audio-only experience suffers when something is shown to viewers in a manner that is not apparent to audio listeners. A podcast series usually features one or more recurring hosts engaged in a discussion about a particular topic or current event.
