On what date did The Late Show with Stephen Colbert premiere on CBS?

The Late Show with Stephen Colbert premiered on CBS on September 8, 2015.

Stephen Colbert took over the Late Show franchise after David Letterman’s retirement in May 2015. Colbert’s debut marked his move from Comedy Central, where he had hosted The Colbert Report, to a major broadcast network.

The first episode featured actor and comedian Jeb Bush as a guest, along with musical performances. Colbert’s version retained the historic Late Show name but introduced a more political and theatrical style.

The date is sometimes confused with Colbert’s final episode of The Colbert Report, which aired in December 2014, or Letterman’s last Late Show broadcast in May 2015.
