All of the broadcast networks aired reruns Thursday night, with CBS far in the lead in every half hour of primetime among both total adults and 18-49 year-olds. Its 8 00 p.m. comedy The Big Bang Theory actually drew 10.2 million viewers, nearly as many as those watching all of the other networks combined. (It pulled off the same feat at 10 00 p.m.) But while CBS shined, NBC produced some of the sorriest numbers ever. Repeat airings of The Office and Up All Night in the 10 00 hour drew only 1.9 million viewers, and it averaged just 2.15 million viewers for the night -- a night that it once utterly dominated with its Must-See TV lineup.
