On September 2, 2009, ABC announced that Sawyer would replace Gibson as anchor of "ABC World News" at the end of that year. Speculation had abounded that either George Stephanopoulos, news anchor Chris Cuomo, weekend anchor Bill Weir, or "World News" Saturday anchor David Muir would replace Sawyer on the program. Representatives for ABC News stated that it wanted to return the show to the original male-female anchor format. On December 10, 2009, Stephanopoulos was announced as Sawyer's replacement, with Juju Chang replacing Cuomo as newsreader; the changes took effect four days later on December 14.
