Meredith Vieira of 'The View' and 'Millionaire' to replace Couric

A day after CBS named Katie Couric the successor to retired news anchor Dan Rather, NBC has picked daytime TV host Meredith Vieira as Couric's Today show replacement.

Vieira announced the move on Thursday's episode of ABC's The View, of which she is one of five female co-hosts.

"I'm thrilled, I'm really thrilled," she told the audience.

Vieira, a former 60 Minutes correspondent and news reporter for ABC and CBS, has also won a Daytime Emmy Award for hosting the game show Who Wants to Be a Millionaire.

She beat a number of internal NBC candidates, including Today newsreader Ann Curry, Today weekend anchor Campbell Brown and MSNBC anchor Natalie Morales. Brown and Morales had previously filled in for Couric while she was on vacation.

Vieira is expected to join the top-rated Today team, including co-host Matt Lauer, weathercaster Al Roker and Curry, this September.

On Wednesday, Couric celebrated her 15th anniversary as host of Today  by announcing that she would be leaving the show at the end of May to join CBS. The network later confirmed that Couric would become the official successor to Dan Rather as anchor and managing editor of CBS Evening News this September.

The landmark move will make Couric the first woman in U.S. history to serve as sole anchor of major network evening news show.
