Stephen Colbert has officially laid his blowhard character to rest. Kurt Andersen, writer and host of Studio 360, discusses the nine-year arc of The Colbert Report and how it impacted the political know-how of its viewers. Plus: Reddit creator Alexis Ohanian (also a former guest on the Report) called in to reflect on the end of the show and to compare notes with Brian and Kurt on what it was like to share a stage with Stephen.

And: a look at the cancelled release date for James Franco/Seth Rogen's "The Interview," which depicts a fictionalized assassination of North Korean leader Kim Jong Un. Sony pulled the release after self-described North Korean hackers threatened violence against American theaters.
