When David Letterman rode off into the sunset, he took a more traditional, structured form of late night televison with him, and what followed is viral videos of celebrities letting their hair down to play games and act out bits. But the new landscape kept one tradition intact, and it’s the male-dominated format. One might argue that there were simply no women in the mix at that level, but a simple bead of sweat would have likely found a female gem. Translation? No one wanted to do the work required to find the perfect female host. They went with what they knew. In a new interview with Tom Brokaw, Letterman shared this same sentiment, saying, “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.” Tune in to the entire interview Sunday night at 7 p.m. as part of the upcoming limited series “On Assignment” from NBC.
