Allison Silverman

Jon Stewart and Stephen Colbert are on three-week vacations, and you know what that means: staff departures and replacements. Allison Silverman, who was Colbert’s head writer from the beginning of the series, became executive producer two years later, and has been as responsible as anyone for shaping the tone of his show, is stepping down. No official reason has been given (because, well, everybody’s on vacation), but the New York Times was informed by a Comedy Central executive that she was just exhausted after four years of working on the show, which sounds perfectly understandable.
