Former "Late Show" host David Letterman granted an interview to Dateline's Tom Brokaw, set to air Sunday night on NBC.
"The first day of Stephen's [Colbert] show, an energy left me and I felt like, Y'know it's not my problem anymore," Letterman said in a preview. "And I've kind of felt that way ever since. I devoted so much time, to the damage of other aspects of my life."
"I couldn't care less about late-night television," he continued. "I'm happy for the guys -- men and women -- there should be more women. And I don't know why they didn't give my show to a woman. That would've been fine."
