The 16th installment of "Big Brother" had a second straight strong premiere night for CBS, delivering Thursday's best numbers among young viewers and combining with a "Big Bang Theory" repeat to help CBS win overall as well.
Thursday's overall race was at least somewhat close because ABC got a good audience -- a series hight, in fact -- for the return of "NY Med," which made a solid overall block with "Rookie Blue," even if demo numbers for both shows are week.
Among other Thursday notables, "Last Comic Standing" is slipping for NBC after a promising start, while FOX's "Hell's Kitchen" and "Gang Related," plus NBC's "Undateable" all slipped a hair among young viewers.
