Initially, the word «podcast» was directly related to the «iPode», the music player of Apple — the famous iPod. Now a podcast, or just a custom, is called a broader phenomenon on the Internet. What, in fact, is cast (podcast)? It does not have in common with Indian castes — social layers, although the word in the plural sounds exactly the same, castes, and sometimes there is a misunderstanding. And it is a form of distribution of media files (audio or video).
