The Big Bang Theory, Grey's Anatomy were each adjusted up two tenths of an adults 18-49 ratings point. The X Factor, The Office, Person Of Interest were each adjusted up a tenth of a point with adults 18-49 vs. the preliminary ratings. Private Practice was adjusted down by a tenth of a point.
Edit: Looking at too many spreadsheets today I earlier noted that The Vampire Diaries had been adjusted up, that was not the case.
