I grew up watching him on most nights. A true comedy legend.
David Letterman announced today, at a taping of Late Show, that he will be retiring. There has yet to be an official announcement, but theword came out through Twitter from those in the studio. Last October, Letterman extended his contract with CBS through 2015. After 32 years (11 at Late Night and 21 at Late Show), Letterman has the record for longest working late-night host in TV history. More info to come later.
