David Letterman’s final show as host of The Late Show will be May 20, 2015.
In April, the longtime late-night host announced he’d be retiring without much information about when—other than that it’d be in 2015. Soon after, CBS announced that Colbert Report host Stephen Colbert would be dropping his conservative persona—and dropping his Comedy Central show—to head Late Show once Letterman’s out.
Letterman began hosting The Late Show in 1993 after heading Late Night With David Letterman for 11 years. Once he retires in 2015, Letterman will be the longest-tenured late night talk show host.
