David Letterman has given to all of us a remarkable legacy of achievement and creative brilliance that will never be forgotten. It's going to be tough to say goodbye, but I know we will all cherish the shows leading up to Dave's final broadcast in May.

After racking up 6,028 episodes of both The Late Show and Late Night, his previous show on NBC that debuted Feb. 1, 1982, Letterman will hand hosting duties of The Late Show over to Stephen Colbert.
