Letterman, CBS sign 'Late Show' deal through 2015

In March 1994, Madonna severely tested Letterman's mettle in an exchange that's become a standout late night moment. Letterman introduced Madge as a top-selling pop star who'd slept with some of the biggest names in the industry, which prompted Madonna to go off a very profane deep end. At last count, somewhere around 13 F-bombs were dropped over the course of the interview.


David Letterman will remain on late-night TV at least through 2015, CBS announced Friday.

Letterman characteristically cracked wise about his new deal with CBS President and CEO Les Moonves.

"Les and I had a lengthy discussion, and we both agreed that I needed a little more time to fully run the show into the ground,"

Letterman said in a CBS news release.

Letterman debuted his late-night show on NBC on February 1, 1982, making comical top 10 lists and "stupid pet tricks" part of pop culture.

He moved to CBS and "The Late Show with David Letterman" on Aug 30, 1993.
