David Letterman planning to retire next year
April 03. 2014 4:47PM
Letterman, 66, began hosting the show on CBS in August 1993, after leaving the rival NBC network, where he had hosted the "Late Night with David Letterman" show for many years.
News of Letterman's plans to retire came nearly two months after Jay Leno bid farewell as host of NBC's "The Tonight Show," a job Leno assumed in 1992 in a highly publicized succession of Johnny Carson that led to Letterman's defection from NBC.
