What is a podcast? According to Wikipedia, podcasting is “a digital media file, or a series of such files, that is distributed over the Internet using syndication feeds for playback on portable media players and personal computers.” Ok, but what does that mean? Basically, a podcast is an audio or video file, like a radio or TV show, that is sent to you after you’ve subscribed to it. The concept is not unlike a magazine subscription. When you subscribe to a magazine, you no longer need to go out and get the latest issue from the store. When a new issue is ready, it’s sent straight to your mailbox.
