Barbara Walters welcomed former daytime star Rosie O’Donnell into the family of “The View” Friday night during the live Daytime Emmy broadcast. Ms. Walters, creator, executive producer and co-host of “The View,” announced that Ms. O’Donnell will succeed Meredith Vieira as co-host on the show in September, when Ms. Vieira is scheduled to debut on NBC’s “Today” show as Matt Lauer’s co-anchor.

“We are thrilled that Rosie, one of the greatest stars in the history of daytime television, has agreed to join us on ‘The View.’ What an exciting way to begin our 10th season,” Ms. Walters said.

Ms. O’Donnell said, “I was touched and honored when Barbara asked me. She paved the way for all women in television, and I can’t wait for September.”

Ms. O’Donnell earned 12 Daytime Emmys as host and executive producer of her own talk show, which ended in 2002.
