  • Have you ever wondered how the Apple Podcast Charts worked? Today we link to its patent application from Apple, filed in 2006. Computing popularity based upon subscriptions appears to contain all the information we already know about the chart: that it’s based upon subscriptions not downloads, and that more recent subscriptions count for more in the chart than older ones (that’s the equation you can see in the excerpt above).
