Diane Sawyer said Monday that this will be her last week on Good Morning America.
In making her announcement, Sawyer -- who joined GMA ten years ago -- said "I've calculated -- 2,881 shows -- Roughly."
Earlier this year, ABC announced that Sawyer, 63, will take over the World News anchor chair, succeeding Charles Gibson, who will retire on December 18.
"You really are giving up your day job finally after all this time," said co-anchor Robin Roberts who added: "It is so difficult. I just keep staring at you. Thank you, we are going to do all things just like you this week."
After Sawyer's on-air announcement Monday, her fellow GMA anchors promised to highlight some of her greatest hits in the coming week, including her 2006 interview from North Korea in which North Korean Gen. Ri Chan Bok warned that war was inevitable.
"It is amazing, I think to all of us, what we've been able to see you do on this show," co-anchor Chris Cuomo told Sawyer. "It makes us all proud."
