I listen to a good deal of podcasts both on and off Earwolf. I hear certain companies advertising on a lot of them, e.g. Audible, Adam & Eve, who have clearly put a lot of money into hoping podcast advertising pays off. Since this is a relatively new medium with an even newer surge in popularity, I wonder, has there been any news as to how well it's paying off for these companies? Is Audible seeing a lot of money out of giving away free audiobooks in every corner of the Internet? This might have been discussed on The Wolf Den or elsewhere, of which I haven't listened to much.
