I agree. Katie Couric alluded to this the other night on the Late Show. Diane became World News Anchors 3 years later and did fine. Although it was in a solid 2nd place when she got there, it stayed there. But Diane also did not have the Perky label like Katie. DI would argue Katie is better then David. I owner if she has joined 10 years alter and went up against David if maybe she would have done better rating's wise?
I Want to add that viewing habits are hard to change. And then there 24/7 Cable News (and Social Media), which has became more in recant years then ever. NBC and ABC ratings have dropped as well.
Yes. The transition form Brokaw to Williams in 2004, (nd I might Couric to Vieira on TODAY in 2006 in which NBC went outside the network and took her away form ABC), was almost ridiculous because of how smooth sailing those transitions were. Those shows stayed in their first place spot. Very seamless. unfortunate some NBC more recent transients have gone over as well.
