Spotted Ratings, Thursday 8/4/11 (FINALS + Jersey Shore)

WHAT MATTERS:

• Season four of MTV's Jersey Shore (4.3) premiered way atop the night in adults 18-49. Nothing in its 10:00-11:00 timeslot even managed a third of the show's 18-49 rating. The Shore was up a tick from its January season three premiere and about 65% from last summer's premiere. Cable's second-biggest program was actually the 11:00 repeat of the Jersey Shore premiere (1.8).

• On broadcast, it was another fairly bland Thursday, though Big Brother (2.8) did tie its season high and had its best Thursday ratings since season premiere night. ABC's Expedition Impossible (1.4) came back down to earth after spiking a bit last week, while Rookie Blue (1.3) held steady against the arrival of Jersey Shore and as NBC's SVU repeat (1.1) gains some traction in the timeslot. Wipeout (2.0) continues to slightly lead So You Think You Can Dance (1.7) and the Big Bang Theory repeat (1.6) at 8:00.

Above based on FINAL adults 18-49 ratings unless otherwise noted.
