Podcast distribution format streaming media
A podcast is a program made available in digital format for download over the Internet. For example, an episodic series of digital audio files that a user can download to a personal device to listen to at a time of their choosing. Podcasts are primarily an audio medium, with some programs offering a supplemental video component. Streaming applications and podcasting services provide a convenient and integrated way to manage a personal consumption queue across many podcast sources and playback devices. There are also podcast search engines, which help users find and share podcast episodes.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, with many podcasts 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 files using RSS feeds to the devices of subscribed users. A podcaster normally buys this service from a podcast hosting company like SoundCloud or Libsyn. Hosting companies then distribute these audio files to streaming services, such as Apple and Spotify, which users can listen to on their smartphones or digital music and multimedia players, like an iPhone. 
As of December 2022, there are at least 2,999,008 podcasts and 152,596,784 episodes.Podcasting is often described as an "intimate" medium. The intimacy of podcasting is constructed through its narrative structure, editing, narration, sound design, and other elements. Sometimes this podcasting intimacy challenges norms of gender and sexuality through its engagement with affect.Podcast novels
A podcast novel (also known as a "serialized audiobook" or "podcast audiobook") is a literary form that combines the concepts of a podcast and an audiobook. Like a traditional novel, a podcast novel is a work of literary fiction; however, it is recorded into episodes that are delivered online over a period of time. The episodes may be delivered automatically via RSS or through a website, blog, or other syndication method. Episodes can be released on a regular schedule, e.g., once a week, or irregularly as each episode is completed. In the same manner as audiobooks, some podcast novels are elaborately narrated with sound effects and separate voice actors for each character, similar to a radio play or scripted podcast, but many have a single narrator and few or no sound effects.Some podcast novelists give away a free podcast version of their book as a form of promotion. On occasion such novelists have secured publishing contracts to have their novels printed. Podcast novelists have commented that podcasting their novels lets them build audiences even if they cannot get a publisher to buy their books. These audiences then make it easier to secure a printing deal with a publisher at a later date. These podcast novelists also claim the exposure that releasing a free podcast gains them makes up for the fact that they are giving away their work for free.
