Allison Silverman had been with series since '05

Allison Silverman is stepping down as exec producer of Comedy Central’s “The Colbert Report.”

No specific reason was given for Silverman’s departure.

She has been at “The Colbert Report” since its launch in October 2005 and, along with Colbert, was most responsible for the day-to-day operations of the show that has seen its popularity rise with Colbert’s faux right-wing pundit garnering headlines and a recent stint as guest editor of Newsweek.

There was no word on whether Silverman’s replacement would come inhouse — Meredith Bennett, Richard Dahm and Tom Purcell are co-exec producers — or if the show would hire from outside the net.

Said Colbert: “It has been a great joy to work with Allison and watch her grow from a devastatingly funny writer to a devastatingly funny leader. I am happy for my dear friend but I will miss her. And this statement would be much funnier if she would just stay and help me write it.”

“The Colbert Report” is on a three-week hiatus and will return Sept. 14.
