Ratings: The Big Bang Theory up 12% beats American Idol easily

Update: The Big Bang Theory adjusted up to 4.7 tying American Idol for the highest rated show of the week. Idol (Results) was adjusted up to 4.0.

The Big Bang Theory was the #1 show of the night with a 4.6 adult rating.

American Idol had a 3.9 adult rating down just a bit from last week. Idol's ratings have been mostly steady for the past couple of weeks, so there is no cause for alarm for the loyalists.

I'm curious to see how the ratings are adjusted later. Big Bang could potentially tie or beat Idol for the highest rated show of the week.
