David Letterman fans, take note: May 20 is his final 'Late Show'

Late night U.S. talk show host David Letterman will anchor his final broadcast on May 20.

The comedian is retiring and handing the reins of the Late Show to Stephen Colbert, network CBS Corp said on Wednesday.

Known for his sardonic wit, Letterman announced his retirement in April.

CBS has not said when Colbert, the host of Comedy Central's faux political news show The Colbert Report, will begin as Late Show host.

Colbert's final broadcast of The Colbert Report is scheduled to air on December 18.

Letterman, 67, began his late night career as the host of NBC's Late Night in 1982. He left that network in 1993 after losing out the host spot for NBC's Tonight Show to Jay Leno.

Letterman's retirement marks the end of a generational shift in the late night TV landscape as networks look to attract younger audiences. - Reuters
