Diane Sawyer, the only woman anchor of a major US network newscast, is signing off from ABC's World News Tonight to pursue new projects with the Disney-owned network.
"After wonderful years at World News, I decided it is time to move to a new full-time role at ABC News," Sawyer, 68, said.
Succeeding her on September 2 at the helm of the nightly newscast will be David Muir, 40, the weekend World News anchor and co-host of the 20/20 news magazine.
George Stephanopoulos, a one-time advisor to president Bill Clinton, will meanwhile become ABC's chief anchor, "driving our live network coverage for the biggest stories", ABC News said.
A one-time TV weather girl in her native Kentucky, Sawyer joined CBS News in Washington in 1978 after a stint on the staff of disgraced president Richard Nixon.
