According to early overnight data, ABC’s “20/20,” which featured Bob Woodruff‘s interview with former John Edwards aide Andrew Young, drew 8.1 million viewers and was the third most-watched program in primetime on Friday, behind two CBS dramas. The episode drew the newsmagazine’s second-largest audience this season. Woodruff recently spoke to TVNewser about the interview, which happened to air on what Woodruff calls his “alive day.”
