Hang on, don't I have a successful weekly podcast that's been running for three years? Well, yes and no. "Podcast" is a term that was coined a few years ago to describe audio content placed on the web which could be downloaded onto an mp3 player. Since the Apple iPod was, and probably still is, the dominant brand in the mp3 player market, the audio files became known as "podcasts", because that is what they are called on iTunes.
For some time, I called the audio version of my email newsletter "The Media Coach Podcast". Then I spoke to some friends at a conference in New York. They showed me some research which indicated that the vast majority of Internet users had no idea what a podcast was, or that they could listen to it without downloading it to an iPod. I changed the name of my podcast to "The Media Coach Radio Show", and instantly found that the number or downloads tripled.
By the way, if you don;t know how to create an Internet Radio show, I wrote a guide to help you.
Creating a podcast is easy, and worthwhile, but what you call it is important too.
