I often am asked "What is a Podcast" Have a look at this 6 minute video for an explanation.
A “podcast” is sort of difficult to explain because there really isn’t anything else like it — but rather, many things that are kind of like it.
A good starting point, is to think of a podcast as “Internet Radio On-Demand.” It’s similar in that you can usually listen to it on your computer but it’s more than that. However, and not to confuse the issue, podcasting isn’t confined to just audio but can be video as well.
