I had not heard of this. Apparently it is relatively new, started with the run-up to the last election and is growing rapidly. A left leaning podcast series.

Jason Zengerle has a fun, insightful read for tomorrow's N.Y. Times Magazine, "The Voices in Blue America's Head," that captures the quick business and cultural success of the Pod Save America empire:
Genesis: "During the 2016 campaign, [Jon] Favreau, [Jon] Lovett, [Tommy] Vietor and [Dan] Pfeiffer ... hosted a popular politics podcast for Bill Simmons's sports-and-pop-culture website The Ringer called 'Keepin' It 1600.'"
Revelation: "More than 1,600 political podcasts — most of them anti-Trump — have appeared since the 2016 election, according to RawVoice, a podcast hosting and analytics company. 'Pod Save America,' with nearly 120 million downloads to date, is the undisputed king of the field."
Why it matters: "With a shoestring budget and no organizational backing, its hosts seem to have created something that liberals have spent almost two decades, and hundreds of millions of dollars, futilely searching for: the left's answer to conservative talk radio."
