David Letterman's final "Late Show" appearance after decades in the hot seat will be on May 20, CBS television said Wednesday.
"David Letterman has given to all of us a remarkable legacy of achievement and creative brilliance that will never be forgotten," said Leslie Moonves, president of CBS.
"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."
The 67-year-old entertainer announced in April that he would retire from the "Late Show."
Comedian Stephen Colbert, known for his political satire, will be the veteran's successor.
Late-night talk shows on the major American television networks are coveted spots for comedians.
Letterman gained a reputation over the years for his off-beat comedy bits and skill as an interviewer of the stars.
Letterman hosted the "Late Show" on CBS starting in 1993 and the similar "Late Night" show on NBC from 1982 to 1993.
By May 20, Letterman will have hosted 6,028 shows in total.
The "Late Show" won nine Emmy awards on 73 nominations.
