Wondery’s audio-only podcasts — such as the true-crime hits “Dr. Death” and “Dirty John” — will be now be overseen by Audible, the audiobook arm of Amazon, and earn money primarily through subscriptions.

Amazon.com is restructuring the Wondery podcast studio by shifting its award-winning narrative podcasts such as "Business Wars" to Audible and consolidating creator-led shows into a new unit, according to a memo seen by Reuters.

Intense competition, high costs and a growing preference for creator-led video have prompted audio streaming companies to diversify their podcasts.
