It hasn’t even been 24 hours since David Letterman announced his retirement from late night, but there’s already an interesting update that sheds some light on what direction CBS might want to go with their next Late Show host. As reported by Vulture, Daily Show correspondent and substitute host John Oliver was approached last year by CBS to potentially take over Craig Ferguson’s 12:30am time slot or another late night slot altogether, but Oliver ultimately chose to go with HBO to develop his show Last Week Tonight with John Oliver. While Oliver’s obviously out of the running now, this update suggests that Jon Stewart and Stephen Colbert are likely to be top candidates for late night CBS – that is, if either of them want the job.
