NEW YORK (AP) — David Letterman will host his final "Late Show" next May 20.

CBS and Letterman's production company announced the exit date on Wednesday. Letterman said earlier this year he was retiring after more than 30 years as a late-night host, and the network later named Stephen Colbert of Comedy Central as his replacement.

CBS didn't announce Colbert's starting date on Wednesday.

CBS chief Leslie Moonves said it's going to be tough to say goodbye, but that "we will all cherish the shows leading up to Dave's final broadcast in May."
