A recorded show sitting on the Internet, waiting. Nobody has to be listening at any particular hour, because nothing is live: it was made, it was put up, and it stays there until someone presses play. One word covers both ends of that — the thing waiting, and the act of putting it there.
From the word’s history
The source's etymology tree for podcast runs through Internet and through pod and iPod, the early pocket player these shows were made for. The common account is pod plus the -cast of broadcast; our copy of the tree is cut off before broadcast appears, so that half is not directly shown here.
字典給的來源鏈一路經過 Internet，以及 pod 和 iPod——當年就是用這種隨身裝置聽這些節目的。一般的說法是 pod 加上 broadcast 的 -cast。不過我們手上的來源鏈在這裡被截斷，broadcast 那一半沒有直接出現，所以只能說到這裡。

以下是外部詞典記錄的用法，摘錄並精簡格式，我們還沒有寫成教學內容。上面的說明才是我們自己寫的；有些用法可能上面已經講過了。
podcastnoun/ˈpɒdˌkɑːst/
- 1
A program, especially an audio program, produced on a regular basis, delivered over the Internet in a compressed digital format and designed for playback on computers or portable devices such as mobile phones.
- There's no restriction for what a podcast should and should not be. Of course, if you cover all these topics and more, you may find it harder to find an audience than if you focus on a narrower range and cover it well. Finding listeners is simpler if your podcast can be summarized in a sentence. More people will sample your show if it fits in a category in a podcast directory—like that found in the iTunes Store—than if it ends up lumped in a generic catch-all list.
- Try listening to a mix of well-known podcasts. You'll soon find that the best always feature hosts that have their own unique voice.
- 2
An individual episode of such a program.
