David Letterman Extends Contract With CBS

It's another two years of  "The Late Show with David Letterman" and "The Late Late Show with Craig Ferguson". They have both re-signed with CBS. This means Letterman will become the longest-running late night talk show host in history, surpassing the late Johnny Carson's record of 30 years on air. Remember where Letterman made his late night debut in 1982? On NBC. His show was moved to CBS in 1993.
