News anchor Diane Sawyer said Good Morning America one last time Friday morning, the date of her final appearance on the show ahead of her move to World News.

Sawyer will succeed Charles Gibson as anchor of ABC's evening newscast, World News. She is due to begin her new time slot on Monday.

Sawyer this morning opened the show thanking her colleagues saying, I'm going to try to take the advice of that immortal philosopher, Dr. Seuss, who says, 'Don't cry because it's over, smile because it happened.' And this morning I am beaming at all of you. My heart is smiling. And the privilege of sharing my mornings with all of you has been more than I can say.

Sawyer has anchored nearly 3,000 shows according to ABC.
