Google is making it easier to find and listen to audio content specific to your search interests, with playable episodes surfaced in results that start rolling out today.

Playable podcasts will show up in results when you use “podcasts” as a keyword in your search, in combination with other terms. It’s intended to deliver you relevant results freed from the confines of a dedicated podcast player, and Google also intends to extend this search feature to queries that don’t even specify “podcast” in future as it refines its algorithms.
