A podcast is a program made available in digital format for download
over the Internet.[1][2][3] Typically, a podcast is 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. Podcasts are primarily
an audio medium,[4] but some distribute in video, either as their
primary content or as a supplement to audio;[5] popularised in recent
years by video platform YouTube.[4] In 2025, Bloomberg reported that a
billion people are watching podcasts on YouTube every month.
