How did fox get a 2.9 this week?
Are you sure Fox isn’t supposed to be a 1.9?
Idol was airing for 3 hours of Fox’s and they don’t air 10pm, but even then Idol wasn’t that high to pull up their floundering lineup.
Fox’s rating this week:
Mon: 2.3
Tue: 1.0
Wed: 4.3
Thu: 2.7
Fri: 0.9
Sat: 1.3
Sun: 1.7
That comes out to an average of 2.0. Rounding can certainly mean it really was 1.9. If you take Tuesday out of it, since there were no commercials, that’s still an average of only 2.2.
It should be a 2.1 rating for FOX; from their ratings press release for this week…

Why is 18-49 considered such an important demographic?
There sure are a lot of 50 plus people who spend money.
I have spent much more money after I turned fifty than prior.
@Martin – It’s not about who spends money, it’s about who can be persuaded by advertising to alter their spending habits. Now that you’re over 50, are you really likely to change your toilet paper brand because the boob tube tells you to?
