It's the end of an era: The Colbert Report is coming to an end. Stephen Colbert announced the last episode of his hit Comedy Central series will air on Thursday, Dec. 18. Colbert is leaving his post to take over The Late Show from David Letterman sometime in 2015.
Colbert made the announcement on the Thursday, Oct. 30 show while urging viewers to buy the paperback version of his book "America Again." His new deal with CBS is for five years.
