Charles Gibson, an ABC anchor, has announced to his colleagues that he is stepping down from being a "World News" anchor, effective at the end of 2009, and Diane Sawyer is set to replace him. Charles Gibson joined ABC News in 1975, and worked on World News Tonight, especially during Peter Jennings' tenure. He worked on other programs like Nightline and 20/20, and after Jennings' death, was thought to replace him, but the job went to Bob Woodruff and Elizabeth Vargas. Soon afterwards, Woodruff was severely injured covering the Iraq War and Vargas stepped aside due to pregnancy, and Gibson stepped to the helm, the program being renamed World News with Charles Gibson. He just announced his retirement effective in January 2010, where Charles Gibson will hand the keys to Diane Sawyer, who's an anchor worth serious instant cash in her own right.
