ABC blew away the competition with FlashForward (3.1), Grey's Anatomy (5.0), Private Practice (3.8). The schedule seems set and ABC will be winning Thursdays for the rest of the year. FlashForward seems to have stopped dropping, so it should be safe for now.
CBS can't even compete anymore with Survivor (3.5), CSI (3.6), and The Mentalist (3.5). There seems to be a good chance The Mentalist will overtake CSI this year. CSI may have a few years left in it, but it seems to be falling quickly. Maybe CBS will consider placing NCIS in this highly competitive slot next year. Who knows...
NBC is continuing to struggle with Community (2.0), Parks and Recreation (2.0), The Office (4.1), and 30 Rock (3.0). Community was up from last week which is a good sign, but is in big trouble along with Parks and Recreation. The Jay Leno Show had a respectable 1.8 against stiff competition.
Fox is doing even worse with Bones (2.8) and Fringe (2.2). Bones is doing as well as ever, but Fringe just can't keep up. Fox threw it to the wolves in its sophomore season which has turned ou to be a mistake.
