Over its tenure from 2009 to 2025, WTF, Marc Maron’s interview podcast, became a meaningful model for the medium—a line late in the book succinctly states that in the podcast universe, “in terms of one-on-one interviews there was a lot of Maron in the primordial ooze.” He steadily honed his craft, connecting with guests by taking a page from his sobriety journey. Many of his first guests were friends from the comedy world, with whom Maron would reflect on their relationship “to see where he may have hurt them…and [get] their perspective on it.” This relational approach helped broaden WTF’s appeal. A 2010 interview with Robin Williams revealed a candid, calmer side of the entertainer—one-on-one, Maron recalls, Williams “didn’t have to do a dance for anyone.” In 2015, President Obama’s visit to Maron’s humble Los Angeles garage studio provided an exponential boost to listenership and more high-profile guests. Episodic rather than exhaustive, this retrospective hones in on WTF’s defining moments. In the mid-2000s, he struggled to find his voice at Air America but also formed a supportive, long-lasting partnership with producer Brendan McDonald. In the 2010s, a patent troll threatened the burgeoning podcasting medium, and, in 2017, Maron reckoned with the cultural cancellation of his friend Louis C.K. The book refrains from digging too deep into the extensive (1,600-plus episodes!) archives of the show but gives a satisfying look into why WTF became such a phenomenon. Brown’s subtly meticulous cartooning sets a visual tone at once intimately comedic and wryly journalistic, a highly appropriate mood for Maron and McDonald’s longtime labor of love.
