Stephen Colbert's 'Late Show' final episode is still a secret

Stephen Colbert’s long run on “The Late Show” ends as he appears behind his CBS desk for the final time. The Thursday night finale's details remain under wraps, but the show has had months to prepare for the end of the network’s 33-year franchise. CBS announced last summer that Colbert’s show would end, citing economic reasons after 11 seasons. However, some, including Colbert, suspect political pressure played a role in the decision. Colbert leaves as the ratings leader in late-night TV. CBS plans to fill “The Late Show” slot with “Comics Unleashed," hosted by Byron Allen.
