Update: Amazing retention for Fringe holds: 13.363 million! House had 14.409 million and a 5.6/16, and 4.9/15 in the 18-49 and 18-34 demographics respectively. Fringe held up in the demos as well with a 5.2/13 and a 4.5/12. Wow. I expect next week really tells the tale on Fringe. These numbers are better than I thought. While there was a drop off from the 1st half hour to the second and it wasn't small, it wasn't as big as I expected. 13.948 million in the first vs. 12.778 mil in the second. Big Brother's finale managed to hold up well at 9pm despite this with 7.63 million and a 2.7 among 18-49 year olds.
The season premiere of House pulled in a 9.0/15 household rating/share in the early metered market reports (please remember these are just an early slice and subject to change). Fringe appears to have benefited greatly from the return of Dr. House greatly scoring an 8.6/13. If those numbers hold up (and we'll see) when we get the fast affiliate data, that's an outstanding retention of the lead-in audience out of House.
I'm drinking the Kool-Aide somewhat as what I watched last night, although slightly timeshifted was House and Fringe.
It looks like Wipeout has cooled off massively down to a 3.3/5 in its season finale. The CW's 90210 scored a 2.7/4 and week two of Privileged netted a 2.1/3. If 90210's numbers hold up, that is better than expected from my point of view as last week it had a 2.8 household rating in the early metered market ratings, so the drop of a tenth of a ratings point doesn't seem steep considering House's premiere.
