Ratings: Gossip Girl and Hart of Dixie Rise, House and Alcatraz Dip

With CBS sitcoms in pre-sweeps repeat mode and Fear Factor forced into airing a rerun by Donkey Semen-gate, The CW saw gains while Fox’s dramas dipped.

Leading out of the gnarly nuptials (and seeming Gossip Girl reveal), Hart of Dixie (1.5 mil/0.6) enjoyed 20 percent gains of its own.
