Charles Gibson is leaving his post as as anchor of ABC News' World News at the end of the year and retire from full-time work.
Good Morning America anchor Diane Sawyer will take the anchor seat, which Gibson has been in since May 2006, beginning in January.
"It has not been an easy decision to make," Gibson said in an e-mail to the World News staff. "This has been my professional home for almost 35 years. And I love this news department, and all who work in it, to the depths of my soul."
ABC News president David Westin said that he and Gibson have been talking about the decision for several weeks and that Gibson "has persuaded me that this is both what he wants and what is best for him."
