The TV news landscape has shifted today with ABC's announcement that Diane Sawyer is stepping aside at ABC World News after nearly five years behind the desk.

David Muir, who had been anchoring 20/20 and the weekend edition of World News, will take over as anchor and managing editor of the weeknight newscast on September 2.

Per an ABC press release, Diane will "lead a team to create and commission original reporting and major interviews for all ABC News programs and platforms [and] anchor and produce television specials and continue to interview the most extraordinary people in the world."

"She is one of the giants of modern journalism," enthuses ABC News president James Goldston. "Her curiosity, passion and energy are unmatched, and I can’t wait to see where she’ll lead us next."

The 68-year-old's decades-long career has taken her to many of the biggest news programs on TV — CBS Morning News, 60 Minutes, Primetime, 20/20, and Good Morning America.

In the same announcement, ABC also announced that George Stephanopoulos, while remaining on Good Morning America, will now be Chief Anchor and will handle special reports and breaking news.
