In a RAIN scrutiny of the newly released Podtrac rankers, we see the clear dominance of iHeart Audience Network in the delivery of podcasts. (Podtrac ranks client neworks, and the rankers, while always interesting, should not be considered comprehensive of the podcast industry.)

As often with ranked lists, we enjoy shining a different light by re-sorting. In this case, we add a column showing how many downloads (on average) each podcast publisher receives per active podcast.
Below is the list of the 20 leading U.S. podcast publishers, sorted by unique monthly audience.
In the re-sorting above, Revolver Podcasts takes the top rank, as attracting more downloads to its single show than some other publishers motivate to individual shows. Note The Walt Disney Company, which benefits from a gigantic roster (53,413 active shows), while spreading its downloads thinly across them with an average 455 per show.
