It’s official: Stephen Colbert is taking over for David Letterman at CBS’s “Late Show” starting next year. This comes only days after Letterman announced his retirement, and Colbert was almost instantly the frontrunner for the position. The Colbert Report host’s representation had casually arranged his contracts with Comedy Central so that they lined up with Letterman’s at CBS — meaning that, when Letterman decided to retire, Colbert would have little trouble moving from one channel to the other.
