According to Semafor:

[YouTube] is currently developing a feature that would allow host-read ads to be dynamically inserted and swapped out within individual YouTube videos

Should make it more appealing for podcasters.

But what’s the long term plan? How does Google monetize these ads? Does YouTube want to become a legit podcast hosting platform? Will it build a host read marketplace?

And how does this impact current efforts to place podcast ads via Ads Manager?
