| The comedian, known for his sardonic wit, 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 Dec. 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 to Jay Leno to be the host of NBC's "Tonight Show."
 
 Letterman's retirement marks the end of a generational shift in 
				the late night TV landscape as networks look to attract younger 
				audiences.
