Business podcasting: how do you do that?

Despite the fact that the phenomenon has been around for about fifteen years, its popularity has been on the rise in recent years: the podcast. A podcast - a contraction of the words iPod and broadcast - is a recorded audio recording from a few minutes to sometimes several hours in which sometimes one, but often several presenters and / or guests engage in conversation. Sometimes radio (talk) programs are also offered as podcasts after the broadcast.
