The season premiere of "Big Brother" pulled a 4.8 Fast Nielsen rating with a 9 share, down slightly from last year's season premiere. It barely lost its time slot to a rerun of "Are You Smarter Than a Fifth Grader?" on FOX, which did a 4.9 with a 9 share.
A second rerun of "...5th Grader" did a 5.4 with a 9 share. Those rerun ratings are very impressive for the show. The ratings helped FOX win the night.
