NFL preseason games televised on cable in local markets probably drew viewers away from broadcast television Thursday night -- because of the holiday, ratings for The Games may not be disclosed until next week -- but CBS recorded solid numbers anyway, leading in total adults and in the 18-49 demo in every half hour, peaking in the 9 00 p.m. hour with 9.7 million viewers for Big Brother 13 . Big Brother was also one of just two shows that were not reruns Thursday night. The other was ABC's Rookie Blue , which attracted 5.86 million viewers at 10 00 p.m., placing second to CBS's The Mentalist with 7.2 million viewers.
