Break PODCAST down into two parts. First the POD: you can either listen to a podcast on your computer or transfer it to your portable audio/video device, which means that file is Portable, and it’s On-Demand because you can listen to or watch it when you want, where you want. The CAST means the file is sent out to you over the Internet, in the way a “broadcast” comes to you over the radio or TV airwaves. But instead of using a radio or TV, with podcasts you use a computer connected to the Internet, and on that computer you have a program that allows you to subscribe to, manage, and listen to or watch your favorite podcasts. That’s where Podcast.com comes in: you don’t need an extra program to listen to or watch your favorite podcasts, or to subscribe to them and manage them, because you can do that right on our site.
