Which comedian became host of CBS's Late Show in 2015 after David Letterman?

Stephen Colbert became host of CBS's Late Show in 2015 after David Letterman.

The Late Show with Stephen Colbert premiered on September 8, 2015, following Letterman's retirement. Colbert had previously hosted The Colbert Report on Comedy Central, where he performed a satirical conservative pundit character. On The Late Show, he generally appeared as himself while retaining a strong emphasis on political comedy and interviews.

Letterman had hosted Late Show since 1993, after moving from NBC to CBS. His departure created one of the most prominent late-night succession decisions in American television. Colbert's first guest was Uber chief executive Travis Kalanick, and the episode also featured Jeb Bush and musical guest Moby.

The program is distinct from Colbert's earlier Comedy Central series. The Colbert Report ended in 2014, and the CBS show uses the longer-standing Late Show title rather than the Report name.
