Jon Stewart's rise from New Jersey kid to the country's most trusted fake newsman is the subject of this Bloomberg Game Changers profile. It opens with his stand-up years at Manhattan's Comedy Cellar and part-time jobs, then follows him into television: co-hosting "Short Attention Span Theater," a short-lived MTV talk show, guest spots on "The Larry Sanders Show," and fill-in hosting on "The Late Late Show." Friends, former co-workers, and journalists describe what changed when he replaced Craig Kilborn on "The Daily Show" and started treating politics as the actual subject rather than a punchline. The film centers on his 2000 election coverage and his non-comedic appearance on CNN's "Crossfire," the moment that turned a satirist into a figure politicians and activists took seriously enough to sit across from. Rare early clips and archival footage trace how a comedy format ended up hosting the kind of guests network news wanted, and why audiences trusted his sarcasm more than some anchors' sincerity.
