podcast

A podcast is a program made available in digital format for download over the Internet. Typically, a podcast is an episodic series of digital audio files that users can download to a personal device to listen to at a time of their choosing. Podcasts are primarily an audio medium, but some distribute in video, either as their primary content or as a supplement to audio; popularised in recent years by video platform YouTube.
A podcast series usually features one or more recurring hosts engaged in a discussion about a particular topic or current event. Discussion and content within a podcast can range from carefully scripted to completely improvised. Podcasts combine elaborate and artistic sound production with thematic concerns ranging from scientific research to slice-of-life journalism. Many podcast series provide an associated website with links and show notes, guest biographies, transcripts, additional resources, commentary, and occasionally a community forum dedicated to discussing the show's content.
The cost to the consumer is low, and many podcasts are free to download. Some podcasts are underwritten by corporations or sponsored, with the inclusion of commercial advertisements. In other cases, a podcast could be a business venture supported by some combination of a paid subscription model, advertising or product delivered after sale. Because podcast content is often free, podcasting is often classified as a disruptive medium, adverse to the maintenance of traditional revenue models.
Podcasting is the preparation and distribution of audio or video files using RSS feeds to the devices of subscribed users. A podcaster normally buys this service from a podcast hosting company such as SoundCloud or Libsyn. Hosting companies then distribute these media files to podcast directories and streaming services, such as Apple and Spotify, which users can listen to on their smartphones or digital music and multimedia players.
As of June 2024, there are at least 3,369,942 podcasts and 199,483,500 episodes.
