It’s not an easy job to answer questions about the statistics of a podcast. Let me explain as simple as I can, cause it’s really a technical matter.
Apple’s iTunes Store doesn’t offer download statistics of a podcast, and it also does not supply storage of audio files. What iTunes Store do offer is a category of podcasts, you can treat it just as an index of podcasts all around the world. We rely on iTunes because of its popularity. iPhone users are growing, and we can gain more listeners around the globe.
