TV's Top News Ladies: Will They Sink or Swim?

With Meredith Vieira's debut on "Today" this morning, the game of musical anchor chairs between Vieira, Katie Couric and Rosie O'Donnell is now complete. So we're left to wonder: which of these women will score big in the ratings and which will fall flat on her face?

Couric scored 13 million viewers in her debut as anchor of "The CBS Evening News" and, while her audience declined slightly by week's end, she still led NBC and ABC by three million viewers. But week two has gotten off to a poor start as Katie dropped to third place on Monday with 7.49 million viewers, slightly behind ABC's 7.87 million and NBC's 8.27 million.

Katie anchored Monday's newscast, the fifth anniversary of 9/11, from Ground Zero and seemed to have trouble holding back tears as she closed the telecast.

While rumors of Rosie O'Donnell clashing with her fellow "View" co-hosts have surfaced (who didn't see that coming?), Rosie's debut on the show also equaled ratings gold -- four million people tuned in, a 54% bump over the same day last year.

Sources have told TMZ that Rosie has complained about the show's production and that Elisabeth Hasselbeck has been openly hostile to her. Rosie even butted heads with Barbara Walters before Rosie even debuted -- Walters didn't approve of Rosie's cryptic blog messages she wrote on her site.

Rosie's rep denies rumors of bad blood, saying, "Everyone gets along great."

And finally, it will take a few days to see how Meredith Vieira does in her new locale, but the former "View"-er did show signs of at least being somewhat nervous (who wouldn't be?) as she flubbed a line on her first toss to commercial break.
