On what date did The Colbert Report broadcast its final episode?

The Colbert Report broadcast its final episode on December 18, 2014.

The Comedy Central series ended after Stephen Colbert was selected to succeed David Letterman as host of CBS’s The Late Show. Colbert played a fictionalized, highly self-important conservative pundit on The Colbert Report, using the character to satirize cable-news personalities and political commentary.

The program premiered in 2005 as a spin-off from The Daily Show, where Colbert had been a correspondent. Its central character, also named Stephen Colbert, was intentionally different from the real comedian, although the distinction was part of the show’s recurring satire.

The final episode closed the series after nearly a decade on Comedy Central. Colbert then moved to CBS, where he began hosting The Late Show in 2015. The two programs are related through their host but are separate productions with different networks, formats, and fictional premises.
