Podcasts

A podcast is a digital audio or video recording, often a part of a themed series, that can be downloaded onto a media player (iPod, MP3, etc.) or computer. (as defined, though slightly reworded, by Dictionary.com) You can find podcast in many different websites, so it's difficualt to narrow it down to one place, though sites like Pod Bean that host podcasts free of charge, as long as you use the basic package.
