February 20, 2009 –

Conan O’Brien made his last appearance as host of Late Night, on this date.
O’Brien, who succeeded David Letterman as the Late Night host in 1993, left the later timeslot to replace a reportedly retiring Jay Leno as host of The Tonight Show. (Intead of retiring, Leno became host of a weeknight, prime-time program; comedian Jimmy Fallon replaced O’Brien as the Late Night host.)
