The premiere of Survivor: Blood V. Water, along with the season finale of Big Brother, helped CBS to win the last Wednesday before the new season in adults 18-49.

CBS averaged a 2.5 rating/8 share and 8.1 million viewers — enough to squeak out a win, according to Nielsen. But Survivor, which is pitting previous players with relatives, certainly didn’t break any ratings records. The premiere was down 19% from last year’s fall Survivor: Philippines (3.2/10 on 9/19/12, 8-9:30p) and earned its lowest-rated fall premiere ever. Maybe we should blame the so-not-wanted return of that ornery player Colton?

Big Brother, which was won by Andy Herren, the least offensive player of the summer, posted a 2.4/7, up 4% from last week.

Fox came in second in the key demo (2.2/7) with the second week of The X Factor. The net boasts that it was up 2% from last week’s premiere in viewers (6.6 million vs. 6.5 million). NBC, meanwhile, won the night in viewers (9.2 million) but came in third in the key demo (2.0/6) with a special run of Million Second Quiz (1.2/4) and part 2 finale of America’s Got Talent (2: 2.5/7, up 14% from last week).

ABC and CW aired annoying reruns. Who’s ready for some originals already?
