Alexa Podcasts is a thing now, because why not.

• Alexa can now generate podcast-style episodes on "virtually any topic"
• Draws from 200+ news publications and "a wide range of sources"
• Users choose a topic, then "adjust the length and direction" conversationally and get a podcast created for them in minutes
• Free for Amazon Prime members

Announcement has examples and suggested use cases. It also hints at "different types of custom audio on demand" coming soon. Custom-generated video episodes can't be too far behind (my prediction, not in the article).
