"One lesson Walters and Couric—and the other high-profile network defectors (Harry Reasoner, Diane Sawyer, Roger Mudd, et al.)—teach is of the non-transferability of TV starpower. TV stars struggle to survive outside of the context in which they were nurtured. The current network anchors—Scott Pelley, David Muir and Lester Holt—all benefited from the fact that they ripened their talents at their respective networks before they got their evening chairs. Viewers grew accustomed to their faces and their styles. Walters and Couric, on the other hand, were hot-house transplants plunged into new environments. Although both women excelled at morning TV at their respective networks, neither ever took root with evening news audiences. The onus can be placed on them—they were rotten at it, you might say. Or the blame can fall on the audiences for failing to appreciate a woman in the nightly news anchor role. Or you can blame the laws of botany. Whatever your call, both were miscast."
