Podcasts are a funny technology: they’re incredibly simple, but for some reason no one really understands what they are, what they do, how to use them, or why you’d want to be in a pod or a cast in the first place. So what’s a podcast? The best way to explain is AP test-style: TiVo is to television as podcasts are to radio and Internet video. That is to say it’s a way to get it on demand, consumable whenever you want. Fast forward and rewind to your heart’s content, and keep as much content as you want – until your hard drive gets full.
You can listen to podcasts on your mp3 player, on your computer, or anywhere else you so desire. They get downloaded over the Internet, and are just simple RSS feeds, so anywhere you’ve got the Internet, you can get podcasts. iTunes is becoming the gold standard, though, and provides a great store for finding podcasts (“store” here is used loosely, because they’re mostly free). Many radio stations are syndicating their stuff to podcasts, and there are a huge number of podcast-only “stations” out there now. Unlike producing a TV show, creating a radio show of sorts, whether it’s video or audio, is relatively cheap and simple to do.
