Stats: The economics of the podcast boom

Despite the fuzzy metrics, or perhaps because of them, right now podcast ads are expensive. According to one recent estimate, podcast ads are selling for $20-$45 per thousand listeners—a number known, in ad-sales parlance as CPM. That’s far more than either radio, network tv, or web ads, which tend to have CPMs in the $1-$20 range.
